Cyclone by maot1985

I have my workbench in my garage and I needed a cyclone for my vacuum cleaner.
There are many cyclones on thingiverse to print, but this cyclones are big printed parts.
The cheapest cyclone on amazon was about 40€, so I decided to make my own 5€ cyclone.
I went to the local hardware store (https://www.bauhaus.info) and bought 2 DN110 HT-pipes (article-no. 13624524), 1 DN110 HT-cover (article-no. 13625530) and 1 DN40 HT-pipe (article-no. 13624490).
I closed one of the DN110 pipes at the bottom with some carton and duct tape.
The other one got a radial hole for the printed part "Radial" and 4 holes for M3 bolts. This is the connection for the vacuum cleaner hose.
The DN110 cover got a hole in the middle for the second printed part "Axial" and 4 holes for M3 bolts.
The DN40 fits in the middle of the DN110 cover. There are holes in the parts "Axial" to mount the DN40 pipe, but the pipe fits snugly.
At the end I used some silicone to seal the parts and I attached 2 M10 bolts on every DN110 pipe for an easier dis-assembly.
On the picture you can see some more duct tape between the DN110 parts. At this time, I had no M10 bolts in the DN110 pipes. With the seals of the DN110 pipes the dis-assembly was very hard, so I had to seal the system with duct tape. After attaching the M10 bolts I used the seals and removed the duct tape.
The stl-parts are not orientated, you have to rotate them with the hose-side downwards.
The holes for the M3 bolts are closed a little bit, in order to avoid overhangs.
The cylcone works awesome. I tested it with strands form MDF and birch multiplex board. No strands in the vacuum cleaner, only a little little bit of dust. To clean the cyclone I only have to remove the bottom DN110 pipe.
