I dont suppose you would be willing to provide the CAD file for the left side would you? I had to buy a different motor from the one you designed it for. I tried editing the stl file with meshmixer but it keeps giving me errors and working with .stl files with sketchup is a nightmare.

<a rel="nofollow" target="_blank" href="/users/nudel470" class="mentioned-user">@Nudel470</a> sorry for the late reply. 4s per rotation = 15rpm and that is approx. 1/3 less than 22rpm. so it might be ok if you let it run 12 hours instead of 9 :-) or you can change the gear wheels to achive a higher speed.hth,Joerg

Hi Nico,I can't remember, that's why it didn't specified the screw sizes in my last post.A good point to start with is a mixture of screws from 3.0-4.5 mm in diameter and lengths from 10mm to 25mm It also depends on what you are tumbling. Small parts = smaller screws and vice versa. hth, Joerg
