Fabricating a missing piece my vintage punch clock with 3D printing. I designed the piece in Fusion 360 and printed it from PLA on my Prusa i3 MK3S.
This is an electro-mechanical punch clock, similar to the Amano 6800/6900 time clock. This particular clock has a National Time label, model number 6907.

The STL file for this part is available for free download on my website: morleykert.com/s/gear.stl
Should have charged 95 dollars for it lol
The stl is available ….For the tens of thousands of people who need it 😂. Nice vid though 👍🏻
I’ve worked for a company that made car parts, and they were practically incapable of making a single piece of anything
Even the prototype runs of a new part went in sets of 5
One time someone ordered a replacement part for a car, we had to make 20 parts because that is what the production run was tooled to do
So that means receive the order, locate the old tooling, run all of the pieces for the 20 parts, paint them, assemble all of them, packaging the parts for shipping, and shipping them using FEDEX rather than putting them in a regular freight truck
It took all day and was handled by over 15 employees over the course of the process…
Then it gets to the company that you ordered the part from, they sell you the ONE that you ordered
And…
Do what with the other 19?
Store them in the hopes that someone else needs it?
Having to count it in tax inventories every year they don’t sell?
Just scrap them?
@@drthmik That makes the 95 dollars look like quite a bargain
You need to send an email to them and invoice them for $100, plus an hourly rate, plus a broken 3d printer file example, and then send the link to the correct online file.
There are a lot of good reasons that that part costs $95. It was the whole assembly, the product is ancient, there is storage, handling, shipping, etc. I am impressed that they were able to diagnose it and offer a replacement part. That's one hell of a company.
He didn't take into account the cost of his 3D printer, Fusion360, and other tools he had available in his workshop. For a collector who doesn't have those lying around $95 seems a fairer cost. For people who does though, yeah $0.09 is definitely more appealing xD
@@jellyfishwiggle8721 Dont forget to mention that he uses a 9 cent plastic part for something that is used over 100 times a day. Image the cost of printing that gear 5 times a day compared to buy one for $95 wich lasts decades
@@ZenoAmbrosius well in the other video he used for reference the part also looked like plastic, also i would doubt that the wear on the piece is actually so much a good 3d printed part would not handle, not 9 cents but i would bet money that if you refine just a little more you can get the same result for something under 10 bucks, hell if don't have the printer you could just order the service online just giving the piece specifications, i'm not saying that the original company is not a good company but i am saying they at least could had told him "oh you are missing a gear that interacts with the mechanism right there" but they didn't, they offered a whole new mechanism to substitute a minor part so yeah not the best
Also no one consider the time he spent. If you work on it more than 2 hours you have already spent 90 dolars :)
@@jellyfishwiggle8721 And youre not taking into account that fact that there's 3d printers everywhere around you. Here in Toronto the libraries have them. That means you could 3d print the repairs locally on a 3d printer for much less than $100. Its free to use 3d printers in our free libraries.
Honestly, I think it is impressive that the company offers replacement parts and support for a 50 year old product.
A lot of companies wouldn't even be able to tell you that there is a piece missing for your assembly, nevermind offering a replacement.
This ^^^^
Yeah, 50 years is some impressive long term support
I wonder if they make refrigerators, stoves, ovens, washers, and dryers too. I would gladly buy my household appliances from them. I'm tired of seeing major appliances breaking down after just a few years when they used to be built to last. Time clocks are found in offices, but so are refrigerators and microwaves.
chances are it's not a wholly uncommon piece? might be a touch hard to acquire but i reckon it's 95 bucks because it'd be casted plastic rather than 3d-print
@@mcfixer9503 95bucks was the price for the complete ink cartridge assembly including the metal frame and the missing gear. and prices for these types of replacement parts that are not the typical wear parts are highly comprised of the additional cost for storage, handling, service, and shipping as these parts of the company are usually not making a lot of money providing massive amounts of replacement parts... pricing is fair for something that is ordered every now and then and 95 is not to make a profit and just to keep this service afloat.
To me, the most impressive part of this video is when he had to iterate to figure out that 10 degrees fits 36 times in 360 degrees.
brainfart :D
Faster to iterate than to engage brain
i was thinking the same thing, sitting here going " 36, its 36.... 36 damn it"
Nothing wrong with figuring things out empirically -- if it works, it works. There is no right way despite what the education system brainwashes you into thinking.
@@tinkeringengr the education system only "brainwashes" the ones who are not very smart or creative to start with.
I always hear people talking about the practical uses for a 3d printer, but it often seems like people just end up printing random desk toys. Really cool to see a genuine, good example of a 3d printers usefulness.
Because most people won't put PLASTIC in something that really needs to function. Imagine you need a surgery and someone 3d printed a piece of your bone
A coworker designs and prints wheel chairs for disabled animals.
@@algoriithmtheproducer They do that... They literally 3d print surgical materials all the time.
The problem is that a lot of people don’t know how to design stuff so they end up printing cell phone holders.
I’ve used my 3D printer more for work (industrial automation) than for random stuff.
It's because mainstream 3D printing isn't done by 3D CAD Modellers, it's done by hobbyists and companies / people trying to make money of cheap toys. The practical use cases for 3D printing can really only be understood by the people that are familiar with the 3D printing technology and how to utilise it to the best of its abilities.
Practical use cases like this are why I finally bought a 3D printer and started learning Fusion. Really enjoying the practical scenarios you’ve been publishing!
Thanks for the feedback!
yeah, 3d printing a part for an obsolete paper stamper is a totally relevant and practical use case...
It’s free for personal use
Totally agree. Much better than videos on how to 3D print an upgrade to your 3D printer or a storage bin for your 3D printer components. Definitely worth a sub.
@@awemowe2830 part broke on a PC steering wheel's desk clamp. Modeled and printed a half dome in like half an hour instead of paying over 50$ for a new assembly with the same fault (weak plastic handle), the 3d printed part allows you to use a normal bolt and tighten it with a wrench
In defense of the company, what they offered wasn't just the gear but the whole array. And to still offer spares for a timeclock looking to originate from the 70's is nothing but impressive. Then, when you factor in the time you had to put into engineering, drawing and then finally printing, for a company paying an employee to repair it, it'd probably be cheaper to just order the spare anyway. But it's a cool hobby project for sure.
Cheers.
$95 is a "why are you still using a 50 year old time clock?" Price and enough to make it worth it to then if you really want it
Yep, not to mention the cost of the 3D printer and software.
Well it depends on how much you value your time. Print time was 27m as shown at 11:26, let's say 25m to engineer it, (think of what to make, measure, model). 2x print makes it 79m or just under 1h30m. At 15$/h that's 22.5$, 30$ at 20$/h.
Not sure whether printing time should be counted or not, but that still ends up being under 95$ for the full assembly, of which just the gear is needed.
So damn passive aggressive
@@rose1770 Depends on the business and stuff, but I know first hand how much things will sell for. I mean: if something costs $30 to make, it often sells for $60 or $90. Also keep in mind that the original would probably be made of metal, increasing the cost to manufacture. So $95 may be reasonable for a company that needs to pay more than a single production engineer, but it obviously isn't for someone with a 3D printer.
8:17 To keep it parametric, the quantity of your array should be "360/toothAngle". That would give you 36 teeth for a 10 degree angle, 72 for a 5 degree, etc. All you would need to do it change your toothAngle parameter and it would automatically update AS LONG as your angle is a factor of 360.
Also love the video! I love to see people using CAD and 3D printers to repair old derelict machines!
"As long as your angle is a factor of 360" -> that's the reason that you should turn it around and say toothAngle = 360/numberOfTeeth.
I was amazed he didn't know how may lots of 10degrees where in a circle.
The thing I appreciate most about old tech, there's no screws. No weird proprietary screws where you need a weird screwdriver to open the product. Everything that needs to be replaced or serviced is on pressure release. We've come so far from that principal that most younger generations think technology is magic and don't even attempt to fix their devices. And rightfully so, as fixing anything now requires a specialist or hours of personal time. What happened? Thankfully, 3D printing is bringing some of this back to the consumers, but it still needs some skill. Better than nothing. Amazing vid, enjoyed watching the fix in real time!
Thank you so much! Agreed, I love old tech.
A lot of new tech comes with parts of the user agreement forbidding "tampering". They want to keep you buying new products. Planned obsolescence.
The lack of screws in modern tech is even worse, you cant open anything up without prying open fragile clips anymore.
And the laws as well. All this subscription rather than owning, enforced by the companies, and the "you aren't allowed to repair it" bull
plus they will void your warranty if you attempt repair yourself.
8:20 a simpler way of doing this is to not specify a tooth angle, but an integer tooth count. You can get the angle from that count (360/count) if you need it. Then you do your circular pattern times that count.
Good tip!
Could you also have repeated the feature, i.e. the cut rather than repeat on the sketch and select all the faces you want to extrude?
@@manyshadesofbrown yep. That's also An option. Probably the easier one :)
@@MorleyKert i screamed at the screen "36" but you didn't listen.
Alternatively, you can specify the tooth count as floor(360/tooth_angle) Algebra!
Props to the company for still providing parts for such an old product. We need more companies like this.
I agree, if you're going to source new-old parts for vintage machines don't expect it to be cheap. It's like if i go to Holden (dont exist anymore) asking for a new-old stock part for a HK (1968 car) and then being shocked at the price of the part? It would amaze me if anyone had a massive stock of new old parts for those cars.
@MeandMyStaffy Because it's a vintage part that isnt produced anymore?... The rarity and time of holding the item makes it's price go up. You've obviously never bought any vintage sought after items before.
@MeandMyStaffy
If it is a machine they do not make anymore then they also do not make parts anymore as well which means the only parts available will be those left over spare parts that were not ordered before people quit using it. That means they have kept those leftover parts somewhere taking up space that could be used for parts they sell a lot more of and maintained the record of their location for decades after people stopped buying the parts.
The company has the expense of keeping parts and maintain records for decades just on the chance that somebody somewhere would have an old machine that they wanted to make work again. Then there is the fact that the rarer something is the more it is going to be worth. That is why gold is a lot more expensive that copper and copper is more expensive than aluminum.
Yeah, it kinda made me mad that he acted like the company was in the wrong for wanting to be paid for storing parts decades after they became commercially useful. Like, "My god! My hobby is expensive? HOW DARE YOU!"
Honestly it should be a requirement for schematics and parts to be made available for everything being made. #RightToRepair
To be fair, carrying assemblies as stock makes a lot more sense than having every part available. A lot of companies don't even sell the assemblies, they'll just tell you to buy a whole new unit.
Thank you for taking the time to show us this. Time is money but the feeling you get when creating/fixing something on your own is priceless. You can't put a price on that!
Thanks for watching!
A couple of years ago, my wife complained about all the 'toys' I wanted, which included a 3d printer. I ended up getting one anyway, and she just rolled her eyes and never really talked about it. When our washer broke, and the manufacturer wanted $79 for a small plastic part, which I printed using a pre-made stl I found online for about $0.30, she became a true believer in the handiness of 3d printing. :)
Heck yeah!
@GREY E CAT no need to “save” any money when you do 3D printing as a hobby
Yep, sometimes telling someone something is not enough, but show them and the penny drops! 🤣😎👍
@@techtinkerin Exactly!
@GREY E CAT My printer cost about $250, but as mentioned by others, I print all sorts of other things with it. I also showed my wife a video that talked about Doctors in inaccessible areas using 3D printers to print medical hardware because it's difficult to get supplies where they are, and the temperature of the heating element effectively sterilizes the product produced. She was quite impressed. This topic was discussed by former Mythbuster Adam Savage in a talk he did called "What happens next? Conversations from MARS"
It’s not the nine cents, it’s the knowledge and engineering, that went into the design. In other words, YOUR knowledge of Fusion is impressive, you did not learn it overnight. Good job!!
and the cost of the printer.
@@OllieVK And the cost of the first test piece = 18 cents.
@@andyu69 and cost of youtube an the charge of the person who put the tutorial on youtube..
The printer, the knowledge of how to use it, fusion and the knowledge of how to use it. The time taken to produce it's several iterations.
Well it cost about over $1000 to print that part.. its a prusa 3d printer which is at least $800 and thats a kit, so you had to make the printer 1st thats at least a few days, then learn fusion which takes around 1 month (it took me a month to learn the basics). Now with all that done you can now print loads of different stuff but you couldnt do any of that without the printer, so a normal company isnt going to do that to save $90 and that $90 is tax detuctable from your companies funds so buying the part is the easiest way and the most cost effective way, it also helps the company who makes the parts employ people.. so doing this you have or could have made a company made some of there employees reduntant 🤔🤔 3d printing is great. Personally i would of made it out of nylon carbon not pla. 😂 so its not a $9 part is it now.. 😂 knit picking yes but thats why we all love the internet ...
This brought me joy to watch… not sure why, but it did! I guess I love seeing reduce, reuse & recycle done so well…
That’s awesome to hear, thanks for watching!
Love it! 3d printing is such a powerful technology. It's safe to say it has completely changed how I think about most of the things I do.
Well the $95 is for the entire piece including the stampled metal piece. It would be nice if they could have offered the gear as a separate replacement part. Goes to show that someone with a bit of skill, knowledge, and patience can achieve wonderful results. Thank you.
Yeah, but I bet they don't sell many spare parts for this thing these days, so even the stamped metal piece probably has a huge mark up on it. Even if you were able to just buy the cog they would have to charge way more than you could 3D print it for, simply because they have to cover the cost of storing them and paying full time staff to ship them out on the rare occasions people order them.
Also, it cost a few cents, but that's only in 3D printer material, it doesn't take into account the other costs involved in making this 3D printed part or the hours of energy spent on making it. Like how much is your time worth, what's your hourly rate? How much time do you need to spend learning how to use the software and getting your 3D printer set up? How much did the printer cost? How much did you spend on electrical energy? How much energy did you use just learning and printing test pieces before you can print that one piece? If we're more honest about this process, if your only aim was to make this one cog, you would have spent way more than $95 to 3D print it. Just buying a 3D printer and getting it set up would cost you more than $95.
imagine if he billed his time out including the assembly and printing as well as the design of the component 2 prints = 50 minutes and then at least 2 hours for the rest of the time , 35 per hour means it cost more to make 1 part, that justification is not sustainable unless you are printing thousands and selling them for 20-30cents minus tax and the cost of electricity...
@@silentassailant3905 and @Red Cube yeah these are all good and valid points I very much agree. I think this was just the appeal point angle he was taking for the whole video so he had to big it up a little. Also I think the lack of people to adequately calculate the total cost of things from all inputs is a fundamental human condition. It's what facilitates companies like uber running their drivers into the ground, as the fares barely cover car maintenance for wear based on miles drover just for uber, let alone a salary. It's also a key point of all this sustainable development goals stuff that's going into high gear, they are going to try and expose the hidden social and environmental "costs" of things, of course it won't be done in a fair or reasonable manner, and just result in exploitative practices and rent seeking, but who knows I hope they change their ways and prove me wrong....
I was about to say the same. Is great to ve able to repair something by ourselves "just" 3d printing it for "cheap" .
Honestly it's surprising to see that the company even bothered to support this request. This time clock is ancient at this point. The fact that they are still supporting it and allowing users to buy parts is definitely worth the $95. Like I get that the company probably paid nowhere near that but still that level of support for a product is insane. I work with enterprise OEMs all day if I asked any of them for a part on a model that was over say 3 years out of production (and not a part shared by in production models) they would look at me like I was insane for asking.
as someone who's still overwhelmed by the complexity of 3d design software, the fact that you had Fusion open for less than 5 minutes is astounding to me.
i didn't even know you could set parameters like that.
there's many many tutorials on youtube that'll teach you different 3DCAD softwares. This design was really simple and If you took just a bit of time to understand the program through youtube, you'd be able to make it in less than 5 mins too( I taught a lot of friends how to use solidworks, it's basically just a bunch of sketching using lines and extruding/revolving)
I love the idea of being able to create replacement parts & products at home in a 3D printer! However I do question the sincerity of this video’s title. The part costs $100 on the open Market! In order for you to create this part on your own, you’ll need a few things. From what I’ve seen, a decent entry level non commercial 3D printer is going to run approx $750 and up! Then comes the real hidden costs which you pay in sweat equity ie. acquiring the knowledge & skill it takes to produce a clean functioning part! At some point, I believe 3D printers will be a fairly common & simple to use house hold item. Maybe never quite like a Star Trek Replicator 😢 but simple & intuitive search engine for 3D models & simple & intuitive printing hardware & software! Not quite there yet. Meanwhile, for most of us dummies, ordering the part online for a hundred dollars is the better way to go.
(Update)- I have had enough people reply to me that I am wrong about the price of good 3D printer. I got my information from the internet about 6 months ago! Apparently prices have gone down drastically since I looked into it, or the info I read was wrong to start with. One guy is telling me he uses his printer “every day” & only spent $170! 🤔 Anyway ok! I got it!!
@@barongerhardt that’s a great idea(visiting local maker shops) thank you. I’ll keep that in mind the next time I am in need!
They don't call it Parametric Design for nothing haha! It is a game changer once you learn it properly.
@@dwmueller76 Although I agree with you , I believe that you are a bit misinformed. You can absolutely buy a good 3D printer for under 750 dollars. My printer, an Ender 3, was less than 200, and it's been great. My friend just bought one and has pretty much been printing straight out of the box, and he is producing good and funcuntioning prints. Ofc you can dive deeper and create better quality but that isn't necessarily needed, not even for this part. It's also not like you would be buying a new 3D printer every time you want to make a part to repair something.
Also the idea of just searching for models and printing them has been around for years in the form of thingiverse and other websites. I have the knowledge to do CAD, but it isn't necessary to be able to do so in order to print what you want. Now ofc in order to print something as specific as what he did in the video, you do have to have that knowledge, but most of us have far more modern things. There a parts online that fix problems with my car, for example.
I definitely do agree that his part cost more than 9 cents, considering even just the basic labor time. But, you also shouldn't discount the ease of fixing expensive things with 3D printed parts, because it's still much easier than your comment makes it out to be.
This is exactly why I love 3D printing! Practical uses and being able to rapidly prototype!
Bravo, a beautiful demonstration of what being able to repair an item you own can be like. Keep up the great work!
thank you!
95 bucks for an original replacement part is actually pretty reasonable. Sound like a decent company!
they could have just sent the gear for a lot cheaper
@@dccatsnatcher2411 Yeah but you know it's a vintage clock. You need to keep the parts in stock for the old model. And keep the guys on the payroll who know how to fix it. And overhead, businesses don't run on thin air. Still reasonable imho and cheaper than 2+h skilled labor to design a one off 3d printed part.
especially for a legacy piece of equipment where they likely do not manufacture replacement parts any more so it is new old stock
@@dccatsnatcher2411 i dont like the pricing either but because of its context i can understand it too.
Its the same with antique car, gun and other machinery parts
@@kwinzman Exactly. Even offering replacement parts for these machines instead of attempting an upsell to something newer is pretty darn impressive.
This is my favorite part of 3D printing! Making little statues and knick-knacks is fun and neat, but there's nothing like the satisfaction of reverse-engineering a part, CAD-ing it up, and then seeing it all come together in a real-life working part 😌
So satisfying!
And you could print out a qr code that has the cad file encoded into it and stick it nearby, so the next person can whip out their phone and download the print file to replace a worn one.
@@Fanta....or print the qr in 3d on the part
Wow, this was such a rad and insightful video Morley! Really great commentary and rundown as well. Subbed!
Thank you so much!
What an amazing video, I enjoyed every minute. Seeing v2 of the gear work flawlessly was so satisfying.
Thank you!
I loved this, but I was so baffled when I heard the measurements in inches. When I started 3d printing and 3d design, everything was in metric and now I can't imagine using anything else for such small increments.
"10 thousands of an inch" "0.021 inches" "0.07 inches" .... What are these weird measurements?!
@@yerwol They’re called freedom units
same, I learned metric because of 3d printing. I mean i already had the concept, but as a wood worker, ive always been a feet and inches guy. metric is so much better for design work.
Same!!! Metric is so much easier for me to understand in modeling software because it's a base 10 system instead of the the base 12 of Imperial units. Same goes for when I make sewing patters. I feel so bad for anyone who would look through my notes because I keep switching back and forth between cm and inches
@@yerwol Eh I mean this is pretty common in machining. The idea of thou or thousandths of an inch is pretty standard in American machine shops. Typically things are described as like "ten thou" or "a hundred thou" instead of .01 or .1
95 dollars.. that's their "we don't want to service this anymore" price
At least they do, other companies would have given you the apple approach and tell you to fuck off
Of course. This is ancient tech and im surprised they still offer the part.
To play the devils advocate, lets say this took 1 hour to model and print (including revisions). Factoring that in, the price isnt so insane. Only business owners would be buying these kinds of parts.
That price also included the metal bracket assembly. We were not told the price of just the gear, if available separate.
@@wilk7255 Exactly my thought!!!
It **is** a tad unreasonable for them to not provide schematics of the gear tho.
How much money should the company spend to warehouse old parts for products they don't sell anymore? They aren't making one-off gears, they had a mold or shop make these by the hundreds. Today, they need to charge enough pay salaries, and keep the stuff around. It's not free, and you can't salary people with a trickle of odd jobs.
As if everyone has CAD design software/skills and 3D printing equipment available to them. I'd say $90 was probably a pretty fair price given how much time you put into this.
save $100 by spending $800
Those savings start to add up.
$100 here $50 there and if you own a mini cooper countryman all4 like I do I 3D print all them plastic connector and mounts because every single one of them is $50.
3D printer $300
Software to run my printer free99
I've saved about $900 already.
There is free CAD software out there and even fusion 360 offers a free trial that lasts pretty long as far as I know.
As for a 3d printer, there are many places where you can order 3d prints. Or someone you know might have one. Although the printer in the video is more expensive, a decent printer these days costs about $200-300. $95 would earn back half or a third of that.
This video was mostly aimed at people who have a means of 3d printing their own designs. The title makes it clear what you can expect.
And honestly the time you would put in a project like this is not that much. this couldn't take more than an evening to do. It costs less (material cost + work time, assuming you already had the printer and software) and it's just incredibly rewarding knowing you fixed it yourself.
He never said that YOU should do the same. He just showed what he did, with his money and time.
@@DraakjeYoblama Skills lacking nowadays when reliant on cheap plastic and cad, could make that out of proper material like aluminium in less than 2 hrs on a lathe and mill.
It's so satisfying to solve a problem, all while only costing 9 cents! Brilliant.
8:21 You had an angle of 10 degrees, and a circle has a total of 360 degrees. Therefore, if you wanted to find the right amount, all you had to do was divide 360 by 10 which would give you 36.
You were a single digit off with 35. Then again, it wouldn't have made a such a big impact, it's just my slight OCD speaking to me.
He already had one in place, so the total was 36 :D.
@@RocktCityTim that’s not how patterns work in this software, the original feature counts as part of the pattern
I was screaming this at my computer!
Should have actually been a formula based on the angle variable (i.e. 360 / ToothAngle) so that it automatically updated when the size of the teeth changed.
@@ktcottrell Funny, I scream at my computer also. Sometimes it pays attention, other times not.
For the teeth on the first gear attempt, remember that you're using 10° slices and a circle is 360° around. Therefore, there would be 36 teeth if aligned properly.
I was just thinking that, myself. At 10 degrees per tooth and 360 degrees in a circle, that would be 36 teeth.

@@genrepolice He copied the first teeth 35 times -> 36 teeth ;-)
Very cool to see your thought process! 👏
Thank you!
The whole point of doing something like this is solving an issue yourself and the enjoyment you get from the process. I needed something to pick up a ball at my mini golf place, but anything I could buy wasn't really practical. Ended up using a plastic bottle lid and a dowel for a handle, and it works great. So, seeing someone solve a problem for themselves with the tools they have at hand makes me smile.
That’s awesome! Thanks for watching 😊
Sounds cool. Do you have a picture? I’m imagining the bottle cap cut in half like a semi circle. Is the golf ball a friction fit?
You might wanna look into resin printers, they are generally better at printing smaller pieces with fine detail. The prints should also be more wear-resistant.
Yeah a resin printer might be in my future!
How much do they usually cost. Sorry , google sometimes doesnt give accurate market price
@@CS-et4fs you can get a small one for 200-300, but that's much smaller than filament printers for that price and prices go up fast for the larger printers. You also need a bit of a hazmat setup to handle liquid resin.
@@patrickkeller2193 "hazmat" is a bit extreme, but you definitely need to take ample safety precautions and make preparations for using a resin printer. It's a 3 step process, in the first 2 steps you need to use and wear nitrile gloves so as to not handle the toxic materials (resin is toxic, and 99% IPA isn't toxic but it will dry out your skin and is necessary for cleaning your prints of leftover liquid resin) The third step is to either leave the print out in sunlight or to place it in a UV light box to cure. Just a pair of nitrile gloves and a gas mask (Isopropyl likes to make fumes) is basically enough for handling the materials. It's suggested to get airtight sealable containers for your IPA and to keep your whole setup in a place that has good ventilation. It's definitely a LOT more work than filament, but the final products you get are still super sweet!
resin printer print really great, but the strength of the part really sucks.
Little tip on for easier teeth generation in cad. Instead of angle, make TeethNumber parameter . In the sketch, drive the angle by 360/TeethNumber (only one sketch). Do the cut of one teeth, and then do a circular feature pattern of the one tooth by using the teethnumber parameter over 360 deg. Cheers!
Or, in the quantity of the pattern use 360/Teethangle. Making use of the already created parameters
These are both good solutions. The first being better for trying multiple tooth angles/quantities, the second being better for quickly being done with the teeth as a one-time process.
That only works if you know that a circle is 360° though XD
learned this in my mechanical engineering technology course. Very Useful!
or made the outer diameter bigger with d(xy)+1 mm and the mm filling lines to construction lines, so you can select the 1 mm bigger full circle to cut out.
this is why i love 3d printing. its for moments like this of being able to fix/replace things on your own. showing how you use fusion also helped me understand why software like this works using parameters.
That’s awesome to hear. Thanks for watching!

A cool follow up would be to buy the part from them and see how it compares to your 3d printed version in terms of design, materials, quality, and functionality.
It would also be nice if he valued his time.
Spending 2-3 hours designing a part, and priting it, means he values his time at less than $30/hr
@@TheDarthJesus nope as he is also generating content so double benefit
That said pla is a poor choice imo
@@francistaylor1822 yeah i agree the fact that he is making a video out of it makes it entirely worth it. for the average person (unless it is just a hobby, or need many of the same part) it would be a waste of time to learn 3D modeling, set up a 3D printer, figure out the dimensions and print a part. for rarely doing it like the average person would it would take a little getting re familiar and trial and error. but I think it is fantastic that he could do this and show people what is possible. For sure it is worth it for a bunch of people but probably not most.

@@TheDarthJesus if he makes it on 9 cents and on his free time, how is it wasting his time ?
He gets to learn by trial and error, and it's something he made with his dimensions, so it's priceless.
That's like working on your personal project and getting to the finished state,
that is something to be proud of , instead of just buying it.
As someone who's always been intimidated by CAD software, I really appreciate that you went through your entire design process in Fusion, even if it is a relatively simple design.
I’m glad that was helpful! Thanks for watching
It is not simple. It is intuitive. I do not see any other creature on this earth able to make such a tool to fix it, but the way a supercomputer, to a computer, then to a printer and coming out with a product is amazing. Old times, a person would carve out a wood piece or clay, then make it into a metal piece by melting steel into it, the planning to make a piece like this on paper and ink, math. Gear ratios, size parameters,Vision to make all the parts work together. It is not simple.
Fair play Morley! Great work on troubleshooting that bad boy and making a cheap solution!!!
So dope man. Thanks a lot for free lesson on how to use this program. Lots of love
Thanks for watching!
I love 3D printing and LOVE seeing videos of people solving problems with designs they come up with themselves. Keep it up!
Thank you!
i love old technology. given the resources and level of tech at the time it's incredibly interesting to see how inventors and engineers designed these machines, and of course most of it was certainly state of the art technology long ago
This was rly satisfying to watch especially how u estimated the part correctly from like 5 secs of video
Love your videos, keep 'em coming! Just wanted to mention a quick shortcut in Fusion 360, after creating your sketch for the single gear tooth instead of using the circular pattern in the sketch, extrude cut the single gear tooth, then use a circular pattern and change the type to "feature" choose the extrude feature and pattern that. This will make a few things easier, one you don't have to select all of those profiles in the sketch, and two you now have the circular pattern in your timeline which makes it easier to edit later on.
That’s a great point! Working on something in Fusion right now where that comes in handy, thanks!
Came here to say that lol
@@MorleyKert Or another way which works fast: changing the circle to a construction-line type so it is open and offset it like 2mm to the outside. You then only have to press once since it is one closed space.
There are many ways...
But very nice to see how you made it.
@@elvinhaak That's how I would have done it too. 1 sketch and 3 extrusions would have done it. This timeline is way more cluttered than it needs to be for such a simple component.
'How many times does 10 degrees go into a circle? Let's say 35.'
You might want to double check your maths there. :)
Great video and I'm glad you saved some money and had fun.
I'm surprised they couldn't sell you just that part. Maybe the originals were metal and so them wearing out or getting lost isn't something they come across often, whereas ribbons and ink reservoirs have a finite life
Lots of things like this are only available as sub-assemblies, perhaps because the company selling the device subcontracted the part to another company, who only sold them the sub-assembly, not the gear.
I hit a situation like that recently with my older minivan with power hatch. The motor drive was fine, as was the arm that went from it to the hatch itself. The ball and socket piece at one end of the arm broke. The assembly could only be purchased together; hard to find, costing a few hundred dollars or so. I was finally able to find just the end piece and attached bolt at a salvage yard for maybe $10 cash, they charged less than normal because they let me take it off the old vehicle myself.
Even if they did buy the cog as a separate component in the first instance, they would have assembled all the sub assemblies at one time, and then shelved the parts for use as spares.
@@almostanengineer More than likely, since their field service techs would replace the entire sub-assembly.
@@bobblum5973 Logistics is a b* and a half.
If your device has 50 distinct parts, you'll need 50 individual boxes. If nobody ever orders these parts, you might as well put them on one pallet and stow them away. If you need one of those parts, you have to dig out the pallet, find the box and properly stow everything again.
In times of free/cheap shipping, this just isn't profitable, unless you make spare parts stupid expensive, at which point nobody is gonna order them anyways.
Super interesting how you're using the parameters and how it all comes together. Thank you so much for this insight!
truly amazing, i come from the days of lathes and miller machines, all work done with micrometers, nothing like you do now, i am amazed
Thank you so much!!
Watching it all come together and seeing the finished product got me so excited. It’s just a piece of plastic for an outdated piece of tech, but overcoming challenges and making something practical just calls out to me
Yes!! Thanks for watching 😊
great job. What I would've done differently though from building almost completely 3d printed robots and other mechanisms:
- model the pin that goes on the opposite side of the ink cartridge separately and press fit it in the gear or glue it. That way you can print the actual gear flat and get perfect outlines. Using supports on suck delicate details won't do you justice . you could even print 2 halfs of the pin so the layer lines are perpedincular to the hole and it will hold better.
- PLA is good for the moment , but i'd suggest using nylon or PC, or at least PETG . both of those materials are easy to print considering you own a prusa. the hotend can take it. You might end up finding that the teeth will grind away over time so something tougher and more heat resistent would be good to use.
Great tips, thank you!
you could print 10 of them and stick them inside the housing as consumables. Maybe even with a QR code on face pointing to this video, for the next guy who ends up needing to make one.
a great option is also to cut a hole and epoxy a metal pin. you can either use machine screws, rods, or for small pins, I've found that welding rod ends are great and don't deform compared to fence wire or electrical wire. and they are also free if you or someone you knows uses a welder.
@@bagok701 I mean at that point better to just specify the dimensions of the part in plain-text in the code itself lol, that way they get the answer faster than 13 and a half mins lol
@@dooplon5083 qr code will probably fit the data for the whole cad file.

Thanks for watching!
I don't know when I would ever need to fix a clock or anything like this, but just watching you go through the process of parameterizing an entire model was immensely helpful as somebody who is just starting to use Fusion360.
That’s great to hear! Thanks for watching 😊
This is a best case scenario for a 3d printer, especially being able to make a part that isn't made anymore or cost way too much to buy when you can just make it yourself at home, when being able to reproduce parts more affordable at home is just the best.
Forget about the part, just seeing a working demo of parameters in fusion has taught me so much about something i was really struggling with, im off to check your other videos, thanks
That’s great to hear, thanks for watching!
There are very few things in life as satisfying as sticking it to the man! Bravo 😄
This is literally the most clear image i've been shown as to how Fusion works, And I greatly appreciate it, Even if I had to sit through 3 minutes of you explaining that a gear is probably what goes into this gear-shaped hole.
((also "how many 10s of degrees will fit in 360 degrees? 35 looks good"))
I'm sorry, I know it's hard, And I do genuinely appreciate the video and will likely be watching more of your content, But dawg. 360/deg is how many teeth you'll get.
I just thought ummm, 10 into 360, how hard is that?
Still. I can't do CAD, don't have a printer, so there's that.
It is (accidentally) good practice to include an odd number of teeth for a part that goes through continuous wear. Unless the step size for each punch operation is 5/7 teeth, That way you do not land of the same teeth every time. The real missed opportunity here was to not use 37 teeth which would've been a prime number (and so close to 36).
@@ShreyasBharadwaj See, What you don't know, Is that I know this already. Prime numbers mean no factors which means no repetitive loads on specific teeth, However, This is interfacing with just a single bar, And if it was made PERFECTLY, It wouldn't matter, As the perfect gear would only advance one tooth per pull. However, That would require measurements on the travel distance of the bar, Which wouldn't be THAT hard, But it would be more difficult.
@@milokiss8276 this is why you've never finished your own projects,,, thinking too much about miniscule improvements
@@AntiDroidZ My man. It's not about improving it... It's that he didn't get the right answer in the first place.
Cheap, but I bet the teeth get worn out fast.
This time clock is a functional display piece......its not meant to be used everyday.
It’s cheap enough to make 1000 of them for the same price, so I think that’s a fair trade off.
You can make things tougher by printing in nylon. Someone replaced a high-speed part of a "Magic Bullet" blender with a 3d-printed nylon part, and it held up fine (though PLA pretty much disintegrated in a minute or two).. Though it will wear out quicker than metal (by a lot), even the PLA will hold up well enough that it shouldn't need to be replaced that often (at which point, just print off another with no design work for like 9 cents)
This function will put very little wear on the teeth. Indeed, the teeth rub against a smooth piece of metal. I think the little knob/bearing on the bottom will get by far the most wear.
Then you print another one
This video taught me so much that I didn't know possible in fusion! Thank You!
That’s awesome to hear, thanks for watching!
Just a heads up, you don’t have to go to the parameters menu every time you want to make a new variable!
You can simply take the shape you’re wanting to dimension, and set its value as
variable_name = *dimension value*
And it will automatically add it to the menu for you!
Dang thanks this is a great tip that I never new
Same, thanks for the tip

So happy I could help you get started! Thanks for watching 😊
Hey @Morley, so its great that your cost of making the piece was 9 cents, but can you share how many hours you worked on this and what you would charge for your engineering skills to create this gear? (This is to give a perspective into the real cost of making things albeit I don't have nearly all the factors there)
Great video btw, I loved that whole engineering process. Just beautiful to see it in action!
Also, how much were the practical elements to make this 9 cent piece in the first place? 3D printer, computer, software, electricity etc.
When you buy a product it's not double the raw product value, allowing for profit, you have to factor in so many other aspects.
Fully agree here, the "it costed me 9 cents instead of 100 dollars" thing is blown out of proportion, since, as pointed out by other comments, it was not the gear what costed 100 dollars, but the whole working piece.
For a proper comparison, the piece that was currently in the machine should be valued and included in the cost of the end product.

Great job with this video, Morley. You did really well showing the iteration process clearly.

Your demonstration of why parametric modelling is the way to go was FLAWLESS! Subscribed!

This kinda stuff is like crack to my brain, it’s just so satisfying making your own parts to save money.
This was a good demonstration and explanation of Fusion 360 basics. For someone like me that is trying to transition to parametric 3D modeling, this was a great example of how to do what seems like the most basic thing.
That’s great to hear, thanks for watching!
That was pretty cool, thank you for that!
Thanks for watching!
This was very well produced. I found your explanations and examples clear and understandable. I enjoyed seeing the whole process.
I was curious about the material of the original gear. It seems the plastic you used would wear out quickly. I understand it can be easily reprinted, but the original was likely a harder plastic or material. I have never used a 3D printer, but it seems to me there would be a way to control the strength of material (using a different plastic composite, etc...).
In any case, thank you for organizing such a relatable problem and solution.
This is an awesome tutorial wether it was your intent or not. Also, if you already have the knowledge, experience, machine, and free time, then 9¢ worth of PLA is nothing. For everyone else, $95 to restore an antique seems pretty reasonable to me xD
Thank you!
I think it also depends on how much the item is worth. If you could buy a working one for $100 it's pointless to spend almost the same amount for just one part, right? I've got no idea how much these things cost though
@@nicjansen230 at that point, any company relying on timeclocks would be better off just upgrading to a more modern system, even if it cost more than a $100 part. last time i used a punch clock for work, it was so prone to errors and failure that it caused payroll screwups multiple times a week. our fool boss would rather spend thousands of dollars on wasted administrative time and employee turnover than implement a reliable system that didn't screw over the workers.
for hobby and learning applications, though, this video is great.
This is exactly what I love about my 3d printers. Being able to print solutions for everyday life still seems like science fiction and is such a fun hobby.

Did practically the same steps to fix a broken piece in an oscillating fan, made the part to fix it but also made it way sturdier than the original part. A lot of useful techniques here! I knew about parameters in Fusion 360, but never really felt a need to use them in my use cases. Perhaps I should use them anyways to gain some familiarity with that feature, so I can see where I can use them where they're most needed.
Nice! In my own experience, parameters are really useful when you have a dimension that you might want to change, and as a way to keep track of measured dimensions.
Using the parameters helps you with how you analyze the problem, it gets you to think of the details and how they interact with each other, so you can identify them more readily in the future. Basically improving your technique through experience.
Yes, I learned a lot. thanks. all the best. see you buddy.
Wow really well done! So exciting when you got it on the second try!
Thanks for watching!
Enjoyed this way to much! Thanks for a nice viceo!
Great job, great way of teaching the viewers as well. Just adding that the piece did *not* cost you only 9 cents. You'd have to take into account the material (so, 2 pieces = 9 x 2 = 18 cents), plus electricity for running everything (printer, computer, room, AC) you used, plus CAD software license, plus *your time*, which is likely to be the most expensive component by orders of magnitude. So we're talking about a few dozen dollars, not just 9 cents.
This is why buying one-off 3D printed parts from companies seems to cost so much.
a rule of thumb just for fdm 3d printing an existing design (i.e. take a file and get a product.) is to take the filament cost and multiply it by 10.
Importantly though, the value of your time only counts if you're doing something you don't want to do anyway. If a movie ticket costs $5, you don't say "well I'm also giving up 2 hours of my time, so actually it costs $5 plus 2 hours of salary". Because the movie is what you want to spend your time on. In the same way I'm sure he enjoyed the problem-solving of making this gear.
And of course if you really want to consider all the costs, you also have to give back credit for the fact that he got 100,000 views on RUclips, which probably means this thing paid for itself :)

I LOVE THIS! this is exactly what i've been using a 3d printer for years now. wel, not fixing punch clocks per se.
subscribed!
just a tip: i've found when printing sharp angels it is better to incorporate the nozzle diameter into the design. so never have two lines come together in a sharp corner, but space them out at least 1/2 of nzzel diameter; that way you do not lose the point during slicing/printing. Also, since the gear is captive, you could have just printed it as a gear with a separate slotted shaft for cleaner result ;-)
Amazing modelling work and great video
Honestly I didn't expect the fusion360 tutorial. I didn't know the parameter function existed, that would have saved me so much time prototyping things.
Always remember the manufacturing constraints you're interfacing with. The punched and injected parts will have burrs and fillets so your design not only has to function it needs to allow for the surrounding parts tolerances. The top boss could have benefited with a fillet radii top and bottom for clearance and strength. The lower axel extended and fitted with starlock washer offers axis alignment and loss prevention. Minor design changes yet so beneficial.
Totally agree with other commenters, $95 is cheap compared to a complete new time system, most manufacturers don't support their product after a reasonable time. Someone in the company's really attached to that puncher, through support by scaling part cost to maintain selling viability, I doubt it makes any fiscal bottom line difference.
360 degrees (full circle) divided by 10 degrees = 36 teeth. So you could just set the no. of teeth to a calculation: 360/toothWidth, and everything is even more parameterized.
Of course, if your toothWidth results in a remainder: 360/11 = 32.72 teeth, you don't have an integer number of teeth, so you have to trunc that: trunc(360/11).
But then 11*32 = 352 degrees, so you'll have a gap at the last tooth of the gear. So you'll have to calculate the actualAngle based on the requestedAngle.
Resulting in these calcutions:
requestedAngle=11
noOfTeeth=trunc(360/requestedAngle) // trunc() could be int() in fusion360, not sure...
actualAngle=360/noOfTeeth
Yup I definitely did not think through this step haha
Also would have saved time to do the extruded cut for a single tooth and then do a circular pattern around your axis for the rest of the teeth instead of selecting every instance of the tooth to cut. But it's easy to have these ideas when I'm just sitting here watching on my phone :)
I love the way you show what you do in fusion 360. I have a better understanding for the program now.
Really neat!! Loved the design and calculations of the part.
Thank you!
Strange that he didn't think about the fact that he used an angle of 10 degrees, then asked how many teeth would fill up the space. 360 degrees divided by 10 equals 36. Loved this video - it's amazing how companies will gouge you because they can.
Not really, because wouldn't it still depend on the tooth depth
@@sir_john_hammond no
I came here to say the same thing. You can see the tiny gap between each tooth. But I guess engineering is about 3/5ths approximation.
What I like to think about when guessing dimensions off of rough things like terribly worn parts or in your case, a shadow print. I like to take the measure and bump it up or down to the next standard size, in your case you got 1.175, which is awfully close to 1-3/16 or 1.1875. Usually competent designers try to get as close to standard sizes as possible. And in your case your acceptable found value of 1.185 was probably supposed to be 1.1875. Now I don’t know if this part was Designed with metric or imperial in mind so I couldn’t know but you can take that way of thinking Into account when guessing a sizing. Great work. It was nice to see you work in fusion, for those of us who have only really seen solidworks/mcam it’s pretty cool getting to see how some other cad/cam softwares work. Very in depth I love the video
Thank you so much, and thanks for the tip!
😂🤣 Competent designers make things standard 🤭, sorry but usually parts are made awkward so you need to go back to the manufacturer to get replacement bits, I'm a designer who tries to use standard diameters and materials but am also a toolmaker who has to repair tools or parts for other people and nothing is standard which is so frustrating when you can see its been done on purpose.
@@ricardo-iw9sq I was always taught to use standard sizes when possible, and as a machinist as well, when parts come by. More often then not values are at a standard sizing on a print. You don’t make things precise if they don’t need to be. Or at weird values. If not you need custom tooling of weird dimensions. If a hole needs to be reamed. Why buy a custom reamer that is pricey, when you can buy one of the standard sized ones for a fraction of the price since they are made by the millions. Obviously sometimes you can’t help it. But say those holes in the stamped sheet metal. Those are made on a press and I can almost guarantee you that they used a standard sized punch to make it because they are cheaper. So therefore the part going in the hole should be close to standard as well. Sometimes an intern won’t be thinking like this when making a part but generally speaking competent designers will know where they can save their company money by using common tooling.
@@knightfall7534 Hi, I totally agree with making things standard but i used to have to repair press tools and the seal sizes on the tool were not even close to a standard either uk or European so we had to get them made special and i did finally convince the customer to alter the tooling and piston groove sizes so they would be an off the shelf item, I have also done bits for cars and they a renowned for being assholes for stupid sizes. When I have a drawing sent to me I will quite often call up the customer and say will a 25mm dia bar work or do you want 24.5mmX 1m and then they say no 25mm is ok its in fresh air, I then say can you ask the designer to look at material sizes other wise its going to cost them, and 9 times out of 10 its a graduate thats never designed and built something from scratch. Happy days 🤭
@@ricardo-iw9sq oh for sure, some people who don’t know the practical side of machining won’t understand why dimensions need to be certain sizes. Engineers who never touched a machine of their life are known for this kind of garbage. But like you said usually they give in and realize it’s better to go with standard sizing at the expense of cash.
Neat ,creative, and amazing way to go regardless of the cost what is priceless is your ingenuity throughout the whole process great video ,may you find much more success .
Congrats on the Million!!!!
Thanks Chris!
setting parameters first is a good idea, no clue why I've never considered that. That would have greatly simplified some of my designs in the past. I've moved away from fusion 360 recently (not even on windows anymore) but the same thing exists in freeCAD.
It depends on what you're designing really, if it's a simple thing and you know what it'll look like from the start, or if you have a complex assembly with a few key parameters that drive a lot of features across a number of parts then it can save a lot of time.
For general design, however, it's just a matter of preference. Personally I think I've bothered to set up global parameters only a handful of times in my career, and of those times I certainly recall times where I've tried to be clever with parameters and it actually causing more trouble than it was worth.
