Fan Showcase

Showcase for the mechanisms contest. Shows off planetary gears, a ratcheting mechanism (meaning the fan only spins in one direction), and a bearing, all driving a fan. Only 3D-printed parts.

Assembly should be fairly intuitive from the pictures, and the number of each part needed is written in the parts description.

Fan blades need to be printed with supports and should preferably be flattened (scaled) down to 65% size (only in one direction, making the blade thinner) before printing.
