"Clockwork" spinning top
thingiverse
Made a planetary gear reducer 1 : 67.5, resulting in a "factory" worm :). The reduction ratio relative to the "solar" gear was 1 : 7.143. I'm using steel BBs .177 Caliber for the bearings and a wooden toothpick as an edge for rotation. The reducer can be assembled without a driver (Carrier, CarrierTop), the main thing is to properly install the planetary gears (attached diagram).
