PlanetaryGearSpinner

thingiverse

I saw something like that on thingiverse but without the outer ring. I also havent got the right bearings so I desiged my own PlanetaryGearSpinner. I like planetary gearboxes very much and i like how they perform. I put 40 M3x10 ISO4762 in the outer ring to use ist as a flying wheel. Try it with air pressure but make sure you wear protective goggles. The inner screw is a M3x20, the 3 screws in the planetary gears are M3x16. The bearings are in the middle two 16x8x5 mm and on the outside 3 standart 608ZZ with 22x8x7 mm. Play around with the horizontal expansion parameter in Cura to find out a suitable value for your printer and your material. I would start with -0.05 mm. Keep printing.
