Rubber Band Torsion Drive Base

Energy is stored by twisting rubber bands, a ratchet is used to allow unidirectional input rotation, and a set of acceleration gears drives a fan to create sufficient air resistance for stable speed. Finally, power is output through a hexagonal prism with a 6mm margin

Requires a lot of grease

Requires glue

Z-seam must be sanded

Use M3 countersunk screws for fastening

Installation steps are as follows

The ratchet can be installed in the previous step, then insert the handle shaft, and secure it with a clamp

A small example is also included

Use 4mmx2mm magnets to connect to the base, the original plan was to fix a boat model on top, but for now a baffle is used instead, which can float up and down with the cam

The project files retain the frame and transmission parts as separate components, allowing for further processing on them
