- To make the cheap sand blaster leak less sand, everyone recommended a vacuum with a cyclone, so lets make one.
I scaled this design from Dronn down to 90% to fit my printer and the european vac hoses 36mm fittings.

Man, I loved watching that printing. That’s one of the best uses of 3D printing I’ve seen recently for a ready to go complex part. I need to get into this. Cheers.
Thanks Anton. That really is a cool part. The designer made a really cool job of it.
The time lapse of the 3d printer is really cool. Nice touch.
Thanks. I am glad I added the hardware and set it up to do those nice coordinated time lapses. They are fun.
Great to hear of the Hubbles recovery, i honesty thought it was going to be futile, those guys are awsome.
Must be a real challenge relearning 1970s control hard and software each time.
Thanks. I love your videos. Lucky been from Australia did not take me very long to learn New Zealandish. Best of luck. Keep them coming
Thanks for the feedback from down under :)
Nice 3D printer work. Also nice to see the 3D printer photography gizmo working well :-) Also great to see your daughter getting her feet dirty renovating, good job.
As for me my Sunday is going to be spent burying the solar array power cables in the trench I dug yesterday in the baking sun but today its torrential rain that has turned the spoil into slurry. grrr.
Thanks. I am glad I did the 3D printer coordinated trigger, as it is cool to see the part grow like that.
We have had some pretty heavy thunderstorms and showers here as well. Good luck with your power cable run.
hi mark,
nice cyclone! I managed to get a filament seller to produce PETG in RAL 6011 Reseda green. I don't get money from him but i share it with guys that print parts for the shop. it should save you painting for the next project. shop is 3DPSP.
in near future RAL7016 Anthrazitgrau is also available. Thats the most common Colorcombo for old machines like DECKEL MAHO and so on...
greetings
Tom
Hi Tom,
I looked at buying some RAL 6011 from you, but back then you only had the new style thinner stuff. My printer is older and needs 2,85mm filament.
That stop frame capture of the print turned out really well in the end, so did the print. It had a satisfying fit once screwed together. I'm glad you explored this solution as it was in my plans for the blaster cabinet build I've started collecting parts for. I look forward to seeing how well it performs, the initial test looks promising indeed.
Oh, and the apple hasn't fallen far from the tree with the kitchen refurb. I hope it goes well and your daughter gets to enjoy the fruits of her labour too.
Thanks. I need to print and install the adapter for the blast cab and see if it works there as well.
I suspect your daughter will be forever grateful with your help in the kitchen. It’s just amazing what people have already modeled up in thingiverse and thangs. Sure speeds up the development process for that one-off you just got to have 👍😎👍
It has been fun doing the kitchen project with her, as she is super motivated with it.
Really. There are a lot of verysimple things on the Thingiverse, but that cyclone must have a fair few design hours in it. Brilliant.
A great tip that was gifted to me by one of my students was to punch a series of small holes in the "gutter" around the edge of the paint can rim so that the excess paint can drain back into the can as you wipe the brush. Also, when you put the lid back on it won't trap any paint under the ridge of the lid. Certainly a manly effort to print your own cyclone. Well done.
Thanks for the tip. Glad that model had already been uploaded, saved a ton of work
That worked surprisingly well 👋
When printing big things like your cyclone I use a 0.6mm nozzle and 0.4mm layer height and those prints finish in half the time. No special settings or hardware while keeping a good finish without shaking your printer to bits. Nice time lapse 👌
Thanks. I can't be faffed changing nozzles, and it really make no difference to me whether it runs for 15H or 30H. It is sitting in the basement beavering away out of sight.
I used 0.2mm layer height to kee the striations down.
Great use of 3D printing! Also thanks for the idea to use big sanitary pipe for dust collection! p.s. cyclone separators make everything better :-P
I had that pipe left over from solvent soaking the Schaublin bearings. Figured it won’t colapse
Didn't know that you are THE Grinch that steels Christmas trees using a cyclone, evidence @ 5:40 :) ... Cool project. Beers, Stefan.
Got to put up pictures of your heros :)
On the topic of painting 3d printed objects: if you want to achieve a smooth finish and remove the layer lines you can use automotive spray-on filler primer (motip spray-putty, is what I have experience with) roughen up the print, spray the first layer, leave it dry for 2 hours, sand it once with rough paper, spray again, dry, sand it once with fine sand paper and you're ready for painting and will get a super smooth result
(This isn't nescecary for functional parts of course, but I wanted to share some knowledge)
I have done that for 3D printed casting patterns, but figured this didn’t merit it. It is just part of a trash system.
For future projects... anytime you need to locate holes from a 3d print, just print a few layers of that section of the part. Perfect solid template.
Great tip. Thanks
Awesome time lapse! And props on the threads, it's incredible how accurate your machine is printing such fine features.
Yeah, it surprised me as well
Pretty awesome use of a 3D printer - the cyclone print turned out great! In the States, we call that paint "Vista Green", and it was one of the most popular shades for Bridgeport milling machines.
In germany that had a DIN standard defining that machine tools were to painted that color :)
@@RotarySMP that’s odd all my machines are painted Aldi paint green 😀 not that I’m cheap or anything!
@@julias-shed I also dont bother with the super expensive 2 part epoxy paints. Figure by the time the paint wears off my machines, my eyesight will have failed :)
Next time you're in the doghouse with your wife you'll need that dog bowl but it'll be too late! It's called "Fido's Revenge"!
Darn...I didn't think that through at all did I :)
it will be interesting to see how well its stands up to the blasting media.
Good point. I don’t think it will be a lot, or hitting at hi speed
Was thinking the same thing, but I think the painted interior should be a good tell-tale
@@JBLewis i suspect the paint will disappear quite quickly, its media blasting after all...
worst case senario he can just print a new one.
@@claeswikberg8958 Good point.
Niiiice. I put a blast gate on my sandblaster and found that the gate got filled up with sand to the point where it became difficult to open and close. I put the gate on mostly because the vacuum has a "T" fitting so it also pulls on another cabinet with a glass saw inside that generates a ton of silica dust laden water spray. The blast gates allow me to select which cabinet to draw vacuum on without fiddling with hoses. I'll have to figure something different out, but for now it's nice to have the gate on there to help keep the sand dry from atmospheric moisture accumulation between uses. (Really only a problem when the garage studio gets below freezing in winter)
Also i 3d printed a dessicant canister that lives inside the blaster.
Thanks for the feedback. A glass cutter must be a sand producer :)
I dont plan to hook up multiple tools. I'll probably just keep this loose and plug it between the tool and the vac as I use it, so blast gates wont be needed.
looks like I have the perfect excuse to buy a larger 3D printer!
Good call. I got contacted by a company asking if I want to review their next printer. Not sure I want to get into reviews much, but it would be a bigger bed with less height.
@@RotarySMP I would love to see your industry experience reflected in the Voron or RatRig build.
@@kttkttkt I had not heard of them. My printer is a modificaton to the Mendel 90. My friend wanted a larger print volume and made the switch to thick MDF as a frame to give decent rigidity and damping. I just copied his design. I have been very pleased with this one, and haven't really paid any attention to the printer market at all.
Man i wish i could work like you. I always find myself stuck in never ending projects i abandon
So do I. Starting the channel has really helped me to focus on finishing projects (not like you would guess frm my last couple of months of scatter shot projects). I really need to finish the kitchen remodel so I can get back to some consistancy on the Schaublin retrofit.
I honestly always hated the green color on the old machines until I started watching your videos and realized how good that looks freshly painted. Now I think the PVC pipe an the blasting cabinet do also need a coat of 6011 to complete the look ;)
Good idea ;)
That seems like a very good addition to any shop vacuum system. Now, just figure out how to make a silencer for it. Mine is so loud that it blocks my brain. Sometimes it seems like the damage is permanent.
I liked the presentation. Thank You for Your time!
Thanks. My vac has the perfect harmonic frequency to be heardthroughout the whole house. I just bought a little battery powered one for the quick clean up jobs and to be quieter.
My ears and brain don’t tolerate noise at all, so I bought a pair of US-made shop vacuum machines that feature “scroll noise reduction technology” or something like that. They work very well indeed at knocking down the high screech that is so common in big vacs. The brand is Ridgid, very common in DIY shops hereabouts; I hope for your sake there is a European equivalent - it’s a worthwhile investment in noise control!
Welcome to the wonderful world of cyclone vacuums. You will really appreciate it when sucking up plaster dust or grinding dust. You know, the stuff that clogs up the filter in the first 2 minutes of use. I like your use of scaling to fit the hoses. I had to cobble together adapters made from ABS pipe fittings and some creative use of hose clamps and lathe work. Good job.
Now I just need to get my shop vac back from my daughters apartment so I can try it with the sandblaster.
@@RotarySMP Good luck with that. One last interesting thing about add-on vortex units. Aliexpress has an aluminum "mini-vortex". It's only about 200-250mm tall and you can gang them together (the inlet is about 25mm). Great for sucking up hot chips or grinding dust. The stuff that embeds itself into plastic (or wears it down). Well made for about $20 US. My favorite vortex is a Red Devil upright I rescued from a dumpster (cut cord). I removed the bottom beater bar and handle and it sits on the wall next to my lathe & mill. Small flexible hose, easy to empty, and oh yeah...free.
@@misterfixit1952 Free, and works... you cant beat that. Thanks for the tip on the aluminium vortex.
Mildly jealous of those having 3d printers now. I've seen a lot of little figures and stuff but that actually seems useful! Thanks for the video!
They are a reall handy tool. Thanks for watching.
I had a handle on my screen door break off about three years ago... designed up a new on in FreeCAD, sliced it and printed it in PLA. Its been outdoors in Canadian weather for three years now and still going strong.
They can be really handy... when you really need a custom part.
Cheers,
@@EngineeringVignettes That is a great use. And it this one fails, printing the next one will need no more design time.
I was actually wondering at first what you'd do to solve the permiability issue of the 3D prints but sealing it with that nice green paint works just fine. I'm sure it also helps to smooth out the funnel like you said.
This is just PLA so I figured it would make it more robust
The walls on this print are massive. No permeability issues at all .I printed this more than a year ago in PETG has been using it since, no post processing, works like a charm.
@@jesperjohannesen1696 Thanks for the feedback. I have only ever printed with PLA.
@@RotarySMP - PETG is the new ABS... only much less stinky. The hotend nossle needs to run hotter (up around 240-250 deg. cel) and use ~ 80-90 deg cel on the bed to get good adhesion. It may be an issue if the hotend uses a plastic insert (as a lot of the cheap Chinese ones do), the "all-metal" hotends have no problem with PETG and higher temp plastics.
PETG is basically water bottle plastic with glycol added :)
Cheers,
@@EngineeringVignettes Thanks. I will have to get a bit more adventurous, but so far PLA has been so reliable, I havent branched out.
Hands up if you were distracted part way though trying to read and translate the newspaper!
:) Thanks for watching closely.
Great job! I think I need to build that cyclone - it worked flawlessly, despite being so small!
I'm still fascinated by the time lapse of the 3D printing (even though I watched your video about it).
Thanks. I am glad I did that printer trigger for the camera, as it makes time lapse way more interesting.
@@RotarySMP Absolutely! It's the best 3D time lapse I've seen so far!
I need to buy some spray cams of that green 😁👌
RAL6011 - Reseda Green.
Nice job!
Thanks for the positive feedback.
Dang it, you just added another project to my busy schedule, now where is one of my 3 Creality CR-10 Max's, they can do 450x450x470 at once :)
Regards from tommylight.
Good call. This is an excellent application for 3D printing.
Careful, once the collection bucket reaches a certain level, the bucket will collapse. If I remember correctly that was roughly the half way point
That is why I used this sewerage pipe. It is thick walled and will not collapse.
Awesome video as usual!
Thanks for the positive feedback.
Great username...I guess? :)
@@RotarySMP We try to give a helping hand when we can. ;)
@@handjobsforthehomeless Generous of you!
Marvelous!
Thanks.
You can increase the performance of the cyclone by adding an inlet with a filter to your container/tube
The whole idea of a cyclone is not to have a filter which can get clogged, but just to separate the particles from the air.
@@RotarySMP it regulates the air intake, if had made your container from a let's say thinner or softer material it would collapse inwards, and that regulation inlet would prevent this from happening. Which adds unnecessary load to the vacuum cleaner.
@@PoYoTheWild That is why I used that strong rigid waste pipe.
@@RotarySMP don't get me wrong I am not arguing or telling you what you did is bad :) just a suggestion.
@@PoYoTheWild I appreciate your input, I am just having difficulty understanding where the filter would go in this system to be an improvement.
I am looking forward to trying it on the sand blaster to see if it works as well as with saw dust.
Thanks for the video. I'm hoping we get an update on that cyclone after you test it in the blast cabinet. I'm impressed with your consistent viewer engagement by replying to every comment. I imagine it's a little tedious, but how is that working out for your channel?
I like engaging with you guys. This sort of channel is too small to attract trolls, so it is almost always nice people who are interested in the content. At this level of traffic, and contents, the answering comments only takes a few minutes each evening.
Yes, once I have made and installed the cyclone interface parts on teh sand blaster, I will give an update on whether it works.
I love that green 👍 i also used it on My rolling tables in the work shop.
I think i Will get a 3d printer for the shop one day forsure
G'day Nikolai, thanks. RAL 6011 really grows on you :)
How is your shop move working for you? Did you get the owner to shift his junk out of your way yet?
@@RotarySMP Ive been slowly getting the shop setup while i work - been really busy keeping up with the work and trying to get the shop setup.. i am far from done - my saws and manual lathe are still on wood blocks and so are my drill presses. i have gotten setup so i can work now but i still need to setup the old mazak mill and the rest of the stuff... the owner of the building is not finish moving hes stuff. its not going to good for him sadly but atleast i can work and hes not in my way anymore. he havent send my a bill for the rent in the new shop neither so thats a plus. :)
@@nikolaiownz You can work around that:) Did you hire any new staff?
@@RotarySMP i made a linked post and on facebook. i had one guy write me but i dident have any cnc experience the past 10 years. i told him that i dident think he was the correct guy for my shop. I am waiting till after the summer vecation (i hopefully go in a few weeks vecation with my family midt next week - and when we get back after this summer i will see if there is as busy as its been the last few months before i start looking again.
@@nikolaiownz Must be a real challenge finding the right staff in Europe. Is it differcult in Denmark to terminate staff which dont work out? Here I believe it is not too difficult.
I have to compliment you on your stop-action, 3D printing, camera video. It took me a few seconds watching before I noticed you never see the hot-end, just the plastic part rising from the bed like it was being beamed in. Very cool effect. How did you time the video pix?
Thanks. It is a cool effect. I did a video on setting that up...
ruclips.net/video/FXXJQMq8srs/видео.html
2:16 That's weird, why is the clock moving? Shaking from the printbed moving?
It is a wind up clock, so as it unwinds the key at the back turns, and it was laying on the key. I thought it looked kind of cool.
@@RotarySMP It does look cool, but the physics of it didn't make sense to me at first. Thanks for the explanation!
@@VorpalGun It is an old Soviet made alaarm clock given to me by a mate who was clearing out his Dad's apartment.
Sweet
Thanks.
Awesome, I have exact same blasting cabinet, it leaks dust even after putting in draught excluder foam. I did use a vacuum cleaner but it was too strong and nearly collapsed the cabinet.
Q1 How will you adjust the vacuum pressure in the cabinet? Make the inlet opening bigger or put a sliding slot (like what the vacuum cleaner has).
Q2 what PSI do you run for the cabinet?
I was going to add an extra port for the vac, so there will be two inlets, the existing small on at the back, plus the filter unit. Hope that will be enough. The second thing is that I will use a small battery vac, with less suction than the big floor unit.
very nice video, I like how the 3d printing work. Nice legs at 6:07 to, yours 😉
Mine of course ;)
What filament did you use? Great video.
Clean PLA. I have only ever used PLA
@@RotarySMP yes, I could see on your setup screen that it was PLA. I use mostly PLA as well.
@@jamescullins2709 I have never taken the time to work out what settings work well for ABS, and it stinks. Some of those lower Shore rubbery plastics look interesting for way wipers though.
@@RotarySMP Thank you for your reply. I think I will use PLA and install a vacuum relief valve in the top. I have seen this done on youtube and it worked well.
@@jamescullins2709 If you look at the latest video I just posted, I printed out an adapter to click into the back of my sand blaster, and it already has a vacuum control valve built into it. I also demonstrated the cyclone on the sand blaster. Spoiler alert... huge improvement.
Could you please test sandblasting 3d prints for finishing?
Can't find anything online...
I doubt that will work. Expect that the grit will just get stuck in the striations, splitting some and partially filling the interior with sand. Probably just make a big mess.
I've always been afraid to ask this but... Do you need washers if you're using lock nuts?
I wanted washers to spread the load, as I am only clamping plastic. If I had larger washers, I would have used them. The nut and bolt head along would put too much localised load and easily crush the plastic.
how durable will that be ; by definition sandblaster sand is about the most abrasive stuff that you can easly get?
It is a valid concern. The velocity through the vac should be substantially lower than the velocity out of the gun.
Hello,
This was the first time I have ever watched 3D printing and I thought actually a 3D printer could be useful... I have already publicly said I will only have one more machine in my workshop - lol, so will meet to fight the urge to buy a 3D printer. See you next time.
Cheers.
Paul,,
Ps. Was the table on your drilling machine scraped?
Hi Paul,
They really are an incredibly handy device. I still sometimes forget to think of 3D printing as a solution.
Yeah, I did a bit of scraping practice on the drill table when I refurbished it. Chicken scratching really. :)
Mark
How much you charge me to make one for concrete for my big vacuum I really need one
Sorry, I don't do commercial work. There are plenty of videos of people making cyclones out of steel pipe and plate though. Should be a pretty easy fabrication job.
Your cyclone is likely too big to be very effective with the fine particles produced by a sand blaster. A good intake and enough negative pressure in the cabinet is usually all it takes to keep visibility in check. I had a small canister vac with a bag over the filter, on my large DIY cabinet, and it never plugged up or needed dumping.
I look forward to 3D printing the adapter and bolting it to the side of the blast cabinet to try it out. WIll be interesting to see how it works with sand blaster dust rater than wood.
How does a vacuum work with a bag around the filter? How does air get through it?
@@SystemsPlanet They are particulate filters, just like the vacuum cleaner bags your mom uses. Most vacuum systems come with them in some form, if they are designed to handle air that needs to be safely discharged back into the area of use - it's kind of a design rule, that the waste air be safe to an acceptable level. Look for "Wet Dry Vacuum Bags" on Amazon. On my sand blaster vac, it was an actual draw string cloth bag, not unlike those on big dust collectors you'd see in a wood shop. No matter what type of vacuum used, it's always a good idea to wear a proper respirator mask anyway. The vacuum is really just there for dust control, not dust protection.
@@RotarySMP Can't wait to see myself... I picked up this same cabinet on sale a couple of summers ago, and want to make some kind of multi-cyclone for it, like household vacuums have à la Dyson Root Cyclone
@@tahwnikcufos Good one. Will be curious to hear your experience of this sand blaster.
I need exactly that but for 100mm pipes.. ;)
You will need a big printer for thst
Music was bumpin
Thanks. Glad you liked it.
@ 5:33 I would loose those burrs from around the hole...
Good spotting. Bit lazy and pressed for time there.
@@RotarySMP Thats cool...
I 2 have done the same & not noticed myself until I took it apart for cleaning...

Thanks. It has een a fun project working with her on that kitchen.
Big plastic carrot... mmm...
:)
3D printing dusts are explosive. Dust collection is also based on calculations that give the the required conveying velocity of a particular dust. Plastic dust conveys at around 3000 fpm. To do this you need a dust collector and not a vacuum. A vacuum is low cfm/high static lift...a dust collector moves air like a HVAC system, but isn't good for vacuuming. For your application you need about 800 to 1000 cfm. A shop vac will never do that. The shop vac also has cheap carbon brush motors that are HIGHLY dangerous around 3D printing dusts. Your entire set up is hazardous. It should be made of a dissipating material and not plastic. Adding a ground wire won't dissipate the static either. Call a proper industrial dust collection company and leave the DIY projects for things like bird houses.
Some good points, but why would the 3D print be producing dust?
rotary scammer ofc promote other know scammers
I dont understand that one??
Bro what?
