Cyclone

thingiverse

I have my workbench set up in my garage and I needed a cyclone for my vacuum cleaner right away. There are many cyclones available on Thingiverse that you can print, but these cyclones require large printed parts. The cheapest cyclone on Amazon was around 40€, so I decided to make my own cyclone for just 5€. I headed down to the local hardware store (https://www.bauhaus.info) and picked up two DN110 HT-pipes (article-no. 13624524), one DN110 HT-cover (article-no. 13625530), and one DN40 HT-pipe (article-no. 13624490). I sealed one of the DN110 pipes at the bottom with some cardboard and duct tape. The other DN110 pipe got a radial hole for the printed part "Radial" and four holes for M3 bolts, which is how it connects to the vacuum cleaner hose. The DN110 cover got a hole in the middle for the second printed part "Axial" and four holes for M3 bolts as well. The DN40 pipe fits snugly into the middle of the DN110 cover, with holes in the parts "Axial" to attach the DN40 pipe. At the end, I used some silicone to seal everything together and attached two M10 bolts to each DN110 pipe for easy disassembly. You can see in the picture that there's duct tape between the DN110 parts at this point - I didn't have any M10 bolts installed yet in the DN110 pipes, so it was a bit of a challenge to take them apart. With the seals on the DN110 pipes, it was very hard to disassemble, so I sealed everything with duct tape temporarily. After installing the M10 bolts, I used the seals and removed the duct tape. The STL parts aren't oriented correctly, so you'll need to rotate them with the hose-side facing downwards. The holes for the M3 bolts are slightly closed in order to avoid overhangs. My cyclone works amazingly well! I tested it with strands from MDF and birch multiplex board - there were no strands in the vacuum cleaner, just a tiny bit of dust. To clean my cyclone, all you have to do is remove the bottom DN110 pipe.
