How I Ruined My Latest Project -

- I became obsessed about an idea to improve the efficiency of producing DIY breathing masks. But through a series of unfortunate errors, I ended up running into a metaphorical brick wall for a couple days. Here's what I was working on, how I screwed up, and what I learned.
Also, in light of the fact that I failed to produce anything useful, I decided to donate my previous month's Patreon earnings to Feeding America. Please consider helping those around you any way you can during these times.

Note: The mask concept I was working on was incomplete in several areas. I had not yet worked out how to install the filter piece in the front. There would have likely been a small printed insert either snapped on, or glued on. Also, I had not yet figured out how to attach elastic to the mask. Most likely candidate IMO would have been to solvent weld small loops to anchor straps to the mask body.

The only true failure is failing to learn from a mistake. This is clearly not that. Thank you for sharing.
Very well said Jack, I'll have to remember this for the future.
Also, thanks to Winston for the motivational pep talk.
My studio has boxes of "failed projects" Each and every one led to better technique and different approaches. Failure is one of the best teachers. Thanks for sharing one of your "failures". I look forward to your next project. I hope you enjoyed your ride.
especially the failures of others, so you don't have to make them again
My shop has a box of firewood :) I have no failures, just fancy fire logs.
Fwiw, after the first couple of times of machining my workholding bolts, I switched over to brass-only bolts, and haven't looked back.
Errors happen every once in a while, but brass' softness makes it much more likely that my end mill will be alright.
Thanks for sharing.
Similar story here but went to nylon fasteners.
Jake Mercer what thread pitch? Don’t they strip? This is new for me and extremely interesting
Every time I mess up a project, I learn something new (and hopefully useful). Thanks for sharing.
Opportunity has not passed. This is not going away anytime soon. I'm a member of Annapolis Makerspace in MD, and the inquiries and requests from nursing homes, hospitals, and emergency services has only increased over the last few weeks. We have been using our resources to produce as much PPE as possible (3d printed faceshields, sewing fabric facemasks, etc) and cannot even begin to meet the demand locally.
I understand the need to protect your mental health/sanity. I definitely go through all of the emotions, from feeling like I've actually done something, to deep sadness that I can't do enough, to extreme anger that it is somehow the expectation that hobbyists can solve a problem caused by our federal leadership who has failed us so badly.
The unfortunate fact is that we are where we are and all of us need to do what we can to make a difference. When and if you have the energy and resources to get back to this, please do. You are absolutely correct about the increased throughput. You can reach a lot of people in a lot of different places. You can make a huge difference. Thanks for trying and putting it out there.
considering some of the areas in china have gone back into lockdown, i also dont see this going away anytime soon.
People are jumping the gun and think it's safe to go back to their regular life when the numbers show a slightly flattened curve. Even governments are mistakenly thinking this.
Thanks for sharing! Your video just gave me the answer to another problem I was having... not because of any particular failure, but I hadn't considered vacuum forming for my project. Until now. Thanks.
Oh man I really wish you can try this again when you have the opportunity! I have a small form factor cnc and acrylic molding seems to be a great alternative to making plastic parts, I'm super interested in this. :)
Amazing that you show other guys that not all projects come perfect at the first time. Great video.
If you are not failing at least half of the time then you are just not challenging yourself enough. You'll never reach your full potential either.
I really respect you for showing a level of vulnerability that few people do. It highlights for me your genuine desire to help people be better
Another great message.
Being able to shift to the next project on the ‘rabbit hole’ list is definitely a learned skill.
I love how you work. Thanks for all you do!
bold man. As a maker with plenty of projects where my idea doesn't completely turn out the way that I expected it is nice to see someone of your skill and talent wrestle with failure. Your projects are so detailed and so well thought out that it is easy to assume that you never fail, but of course, we all deal with failure. Thanks for being real and releasing this for us. Much respect.
I'm a cnc mill programmer. The shop I work at does a lot of one off parts in stainless and other heat resistant materials like Inconel, monel, etc... Nailing our 'projects' the first time around is our game... Failure (though a great teacher) can get expensive fast and it doesn't take much
I hang my CNC failures on the Wall of Shame in my shop. Not to dwell on the mistakes, but to remind me of the missteps and how to avoid them in the future. Thanks for sharing yours.
I totally know what you feel about failure. The disappointment from it sometimes seems very out-of-proportion to the actual failure. Thanks for posting this video. Even though it didn't work out, it made me think about using tools together in a way I didn't before. And who knows, this might work out in the future now that you've overcome the mechanical failures that set you back here.
Mistakes are another word for experience and mistakes are the tuition paid for success. The fact that you have the mental fortitude to do a post mortem on your project speaks volumes about your intellect. I appreciate you sharing, thank you.
I had some of your issues too and learned a lot about the reproducability of homing./zeroing My cnc controller board is susceptable to ground loops and locks up sometimes. When it happens I have to rezero. Sometimes you machine away your reference points. What I do in those cases is use the homing switches, zero the axes, then read the machine coordinates of the zeroed axes and copy/paste them if and when the board locks up. This has saved me so many times. I use a laptop instead of a desktop pc now and the lock ups have never happend again but on important projects I still use this technique.
Great video an it is awesome that you uploaded this video content. It shows even the experts have failures just like most of us. I am new at this and have failures, but I use them as learning moments for future projects. Thanks again for sharing, I do immensely enjoy your content so keep up the great work.
The Buck can still be 3D printed, and used as a vacuum form....if you print in ABS the vapor bath for smoothness....
Thank you for sharing. There's always something to learn. Looking forward to when you revisit this forming concept.
Small point really, but the holes on the wrong side could be fixed with what we in Australia call Builder's Bog - probably Bondo in the US. I have saved numbers of projects where I have removed material I shouldn't have, with the judicious application of Bondo. I'm not sure about how secure it would be to apply Bondo the outside of your model and then re machine it - maybe roughening the surface so it could "key in".
I make a lot of mistakes and an advantage of that is learning techniques of how to rescue disasters.
Posting before finishing the video -- I wanted to add...we have a vacuum former at our makerspace and it is a fickle bitch. One big thing I've learned using it is when possible...use a negative form instead of a positive buck. The positive shapes almost always have folds around the peripherals where joints don't pull smoothly. As the vacuum pulls, the majority of the material is eaten up by the form leaving little for the void, resulting in stretching.. The justification for suggesting negative space is - look at the solo cup. As the material draws into the void it experiences the same forces on all sides, leaving the majority of the material to comply in all directions outwards.
Addendum after finishing the video. Thanks for sharing and trying to do your part. It definitely can be frustrating when every part of a project goes sideways. when the machine that makes the machine breaks it it hard to not 'blame your tools' but in this case it's worth the mental credits. Enjoy that sun!
Fascinating. I just had almost the exact same series of issues with a project I was working on.
Same machine issues, same homing errors, everything. This has totally helped me get over the frustration I've been having and I'm going to go make some improvements!
I am glad to see I'm not alone in suffering failures with fusion and my CNC machine. Thank you for sharing excellent work. Better luck next time.
Learning from mistakes is the best way of learning, at least for me. It's the only way I remember it permanently.
You should continue. Like other people said it isnt going away soon and this is a great idea.
Thanks for sharing your mistakes. It's important to be OK with failure and encouraging people to experience that and still move forward means quite a bit in today's atmosphere. Thank you.
Great to see the process - and I echo that the opportunity has not passed (you may not want to hear that :)) - I think it is a great idea to vacuum form. This has shown that 3D printers are an amazing tool - but that they may not always be the 'production' tool unless you have volume (a farm) - despite having 3 printers I have used the laser cutter for shields and it can churn out 100 a day as pooped to 5. The meds have also commented on how easy they are to clean overnight. So I love the different path, and they were mistakes we all make (I just recessed bolts on the wrong side of a frame for a deck chair - who does that!)). Keep doing what you are doing!!
Thanks, I appreciate failed attempts as they show the thought process and that is often good for inspiration.
keep up the good work! We learn more from our mistakes than our successes.
Great video! You made it further than most of us lurkers have. You made an impact whether your project succeeded or not. Thank you.
This is the first video i have seen on your channel and you knocked it out of the part. Liked and subscribed. Can't wait to see more from you.
The vacu-forming concept is excellent - 3D printers are being used en-mass to fill the gap until injection molding can ramp up for this PPE, but vacu-forming is a great intermediate step.
Thanks for sharing your frustrations - these hobby-class machines (includes almost ALL 3D printers) are fantastic, but they aren't super rugged, and seeing the kinds of flaws different failure modes can create is helpful to everybody in diagnosing problems. The runner wheels on your CNC machine, for instance, are almost exactly how most delta-arm 3D printers work, and a similar shift in a printer would result.
You continue to inspire, even in your "failures".
I have been down this road many times my friend, the things you learn from the process make your future projects run much smoother.
Awesome video. Thank you for posting. I am experiencing some of this myself...glad I'm not alone with the whole "sprint, then fail, then walk away" process.
Always enjoy your content and appreciate your honesty.
Ever thought about creating a mold for a mask, but create it using the top of a PET bottle, Heat it up and press it on to form the shape, then, you only need an adapter for the nozzle/screw thread to a suitable filter. Was going to peruse that here, but we are lucky enough to not have been that badly effected.
Seems like a great concept that just went wrong because of the machine being slightly broken?
The go-cart thing - reminded me vaguely of Richard Feynman's critique of the top-down design of the Space Shuttle's main engines which had similar issues - well worth a read!
Name of the book?
@@pickerjim9246 It's published online - on Feynman's website in plain text I think
good man Winston.. there is no failure when knowledge and experience have been gathered 👍👍
What you accomplish with the shapeoko is astonishing. Good enough is good enough when lives are on the line. Hit that shift with a Dremel and vacuum form to your hearts content.
You counter bored your holes on the wrong side. I appreciate knowing that someone I admire makes the same stupid mistakes that I do!
Hi Winston,
i am from germany where we also had the same idea like you, we are working still on a mold, but we 3D printed the mold out of ABS instead to mill it. Currently we dont have any possibility to get on a vacuum forming machine, because the machine is in a university and, you guess it, closed. I hope you can go further with this project, because this is exactly the aproach where we was thinking this would be possible to cover the most neads for masks.
Please keep us up to date. We would be so happy.
Best greetings from germany and please stay healty aswell your family and friends also.
Michael
Failure is the BEST way to LEARN. Don't ever give up, just try something else. Everyone FAILS more than they succeed, but it's those that keep trying and eventually succeed that change the world. It is the success that defines us, and how we pick ourselves back up for the next attempt, it is NOT the failure that defines us rather it is the failures that we learn from which is what makes people successful!!!
@Winston Moy, Love your videos, can you please explain how you are using different size of end mills and drill bits with makita router, makita has a 1/4 collet right? is there other sizes of collets for makita router. Thanks
Hello, I will dig up the topic a bit, very interesting material, I have a question, what material did you mill it in? and I was curious about the method of finishing milling, where did you mill the top and bottom with what kind of milling cutter? and would it be possible to share this file, because soon I will have several complicated forms for milling, this method seemed very interesting to me and I would like to get to know it better :)
Great video, I teach high school woodshop and CNC and learned a ton from this video. Thank you
Good on you for all points made!
Winston, part of learning is making mistake, what I love about these video is what issues you have found. Such as the machine had issues, that is the problem I found with my CNC machine. Typically you think your machine is working in perfect order and find why it did not come out. You are very proficient in fusion 360. The second wave will be something that will cause more PPE to be available for our first responders. So I would not give up on this mold.
use some bondo or wood filler and sand it into shape. it's a vacuum form, it doesnt have to be perfect, just has to work.
Awesome video great to see potential problems that I may see when I get my machine. Glad to learn about but positioning of the bit a zeroing. 🎨🤙🏼🎣 thanks for the info.
Great video! Thank you! We are all in the failure boat most of the time. I really learned a lot from your video...
Thanks Winston! Stay well, see you in your next vid!
Works great! Do it all the time in film industry and rapid prototyping. Try using a very high density carving foam instead of mdf. Easier to finish by sanding and poly primer. Or you could print one with the same concept of having flanges for a return edge, finish with high build primer and mold that.
Plan A for me would have been to use Renshape, but that would have been way pricier. Need to find a cheaper alternative..
@@WinstonMakes xps
It happens to us all..... Good idea with the vacuum forming though! 8 have been meaning to make a vacuum forming set up for a while....
Ouch I had the same problem with HDZ upgrade today... My bearing holder at bottom was loose and screws on the HDZ linear rails unscrewed and popped out on both sides. It freaked me out when I heard a crash when gantry moved up to switch cutters. I really hope HDZ won't give me problems now :(. Side note though, the HDZ is really awesome and a great upgrade! Just add lock tight if you get one.
Yea, it's always good to "trust, but verify" that everything's been tightened down. Set screws are the most common thing that need to be double checked.
Ironic you should post a video about failure and projects as I just put together an aquarium yesterday and it seems like I’ll be doing it again today. C’est la vie. Stay safe bud!
You were so close! Keep going!
Thanks for sharing.... and carry it on! 👍
I'm in the same boat! Almost identical. Want to make a vacuum mold but my 3018 mill just sucks!
2:50 You scored 100% for Darth Vader look-a-like face mask!
I'd consider ditching the V-Rollers and make the switch to linear rails. Even inexpensive non-hiwin knockoffs work well when cleaned and lubricated properly.
I've seen a couple users make that modification to Shapeokos. Haven't ruled it out myselff...
While I don't wish failure on people. I like seeing this. Failure is the fastest teaching tool for many people.
Great video Winston! =)
Don't they use nylon lock nuts on those bearings? I am just a new engineer thinking about getting a shapeOko and was wondering why they don't use a more resistant nut?
Yep I saw the rainbow too. Light at the end of the tunnel. We will make it through this!
Hello Winston, I'm a tool and die maker at a food container company (Genpak) we use thermoforming to make our product. You sparked my imagination of using the process to make your design. When we are prototyping a new design it's time from concept to product in hand could be a time problem. Any way if I could help you in any way please ask. Like your narration while watching your video.
Well, looks like I won't be going with that Carbide3D machine. I'm not a fan of those V-Wheels on a gantry router. They are already using linear rails on Z axis, why not on the gantry X axis?
Create a return lip at the bottom of the form. Will make the edge smoother, and you can punch holes into it for the mask straps.
We just printed and sanded our tool. Works great. We print thermoform tooling all of the time at work for short run parts. Just have to monitor your tool for heat soak if you throw it into a production machine.
Picture of our first prototype: Montana thermoform imgur.com/a/Gtuz6iK
Good information.
I have one of these days at least once per month, sometimes it's once a week. I appreciate the reality, we present ourselves as perfect and everyone makes many mistakes - daily.
Yep know that so wel not being able to trust your macine is truly discouraging I have so many projects on halt because of that including fixing the problem in the first place
In aviation, pilots do a walk-around to check the critical parts and functions of the plane. Perhaps this could be used for all tools.
Man, CNC CAM it's still hard to do. Way harder than 3d printing. But...
You can make to mould for vaccum forming in a normal 3d printer. I don't think it will melt.
Awesome video. Takes courage to show the "failures." We all learn from it. Mahalo for sharing! : )
Your successfull rate is pretty good. I made so much prototype for whatever I make that I do not even count the first attempts...are all pre-produciton models :-)
You did not fail. You just worked out the bugs. It takes me about 3 tries to get things perfect.
Take a break and then get back at it and you will see all is good.
As a perfectionist myself I hate failures sincerely. Sometimes they happen. But giving up is never an option!
Thanks for sharing Winston. As the others below have commented, when we learn from our mistakes, they become as valuable as when everything works perfectly. What sort of cover do you have over your router top? Also, how have you installed the blower, where did you get it, etc.? thanks
It's just a regular sock I cut a slit in,to get around the power cord. Then I used a strip of velcro to close it up again. It's mainly to keep aluminum chips out, don't need it for wood or plastic. Meant to catch big particles, not filter dust. The latter would restrict airflow too much.
Perfect! And what about what appears to be a blower coming down the side of the router? Great idea, but I cannot find one. thanks.
It's a flexible coolant nozzle that I've connected to a 950 GPH air pump for hydroponic systems. Helps get chips out of the way when cutting aluminum in deeper pockets.
got it - thanks again
comments below
or above
depends on how you think about yourself
Fix it with some filler and hand sanding! It’s close enough to save and make work for the time being
That's what I was thinking, just use some automotive bondo and sand it smooth.
Perfection is the enemy of good enough.
Winston, I was against you shelving the project until you made mention of doing so for your own mental health. Exercising self-care is an important aspect of good self-leadership. So, good for you. It seems you took away other valuable lessons from your so-called "failure", and that's a good thing.
I, for one, don't view your attempt at machining a buck to thermoform respirators a failure at all! Aside from the homing/zeroing error, the ball screw and v-wheel fracture that led to the mis-machinging were both out of your control.
So, once you're back in a good head space, get back in the garage, repair that CNC and get back to the brilliant work of which you're so capable!
Thanks for the incredible view of the rainbow at the end!
Be well and do good work!
It's a pity it failed. Would've love to see a finished product!
Regarding the counterbores in the wrong side... plugs glued in would repair that easily...
Plastic wheels should be replaced with brass at least... for longevity (do u have a small lathe ?)... and really... machine-maintenance is something you should be doing on a scheduled basis... as a production engineer, I have learned over the years that prevention is paramount... ALL manufacturers have maintenance-schedules , they can't afford unscheduled downtime in the middle of a run. 🙄
Not beating ya up here, just making some suggestions.
Good luck !! 🙄🙂
😎👍☘🍺
How about cutting with indexing holes, where you can put dowels later and stack them. You might need to sand it later anyway. Or just 3D print it. :D
It is the most necessary trial in this period and I wait for the next.
Wisdom through humility
Maybe you didn't show it well, but I'm at a bit of a loss as to why you gave up. Your finished positive is slightly imperfect from your mistakes, sure, but a little sanding paper and you can have a decent chance of vacuum forming from it without issue. A vacuum forming rig from Shapeoko would be a great product!
Success is falling down seven times and getting back up eight.
You could add bondo to the tool and remachine after a few mins.
Failure is (almost) always an option. Often a good one. Cant learn much if you always succeed at some level.
Brilliant Idea! I would love to see you attack this again. Your router skills are far greater than mine. However, I'm going to try as well. My wife is a nurse. Everyday I hear horror stories of having to reuse PPE because replacements just aren't available.
When every failure probabilities aligned
Failure is important. My friend 3d printed one of those masks and it was pretty crappy. I like your idea to vacuum form, but the process of creating the buck was way more complicated than it needed to be. That profile could be sculpted out of a piece of wood with an angle grinder and a flap disk.
sweet rainbow!
what exactly is the HDZ you refer to? is it a 'hd' z-axis mod for the shapeoko?
Not a mod. Officially supported upgrade: shop.carbide3d.com/collections/shapeoko-hd/products/shapeoko-hdz?variant=31279490531389
..... why not 3d print the form?? It may take some finishing but its bound to be easier than a multistage CNC process.
Any chance you can upload the making of the mask in fusion at normal speed? Always wanted to know how to loft along a guide
It takes a lot of courage to admit to have failed at something. The world shows only the successful stories leaving those who have failed behind.
Heads up, because one knowing where he has failed, will learn from that, thus improving his skills.
Thanks for the video. I learned a lot from it
I have in my head another idea.. Injection silicone and making "mold form from 3D printed part.. However curing is too long and I dont know if it is worth to make it done.. I have only basic model in Fusion
you are so lucky to have sunlight. we had snow today!! :(
I've been waiting for a cosplayer to make a Bain respirator mask, I mean this design is half way there!
Cosplay for the win. I finished my Subzero filter mask last week!
Why not make a 3d printed vacuforming mold?
My biggest concern was that hot ABS, which was the sheet material I sourced, could fuse to the PLA (only filament I have). BUT... Instead of worrying about hypotheticals, sometimes it's best to just try it. When I get around to making a vacuum table I'll give it a try on a smaller scale.
@@WinstonMakes
You will probably have to coat the 3d print in epoxy anyways to smooth it out. Maybe print the design and coast it in a thermally stable material? Then you can make multiple mask forms for each run.
