Rubber band Powered ThinkFun Motor

thingiverse

This is a Rubber Band Powered System used in ThinkFun Creations. Connect a rubber band over hooks on Side Support and Rotor parts. Turn the Rotor to tighten the rubber band. Release the Rotor to activate movement of your creation. This system uses ThinkFun Rods and Hub Caps for connecting the Rotor to items you want moved, so long rods can be used as drive shafts too. The large radius of the Rotor creates extra torque for motion. Side Supports connect with other ThinkFun connectors, but a fifth hub cap is needed for the Rotor and drive shaft rod. Space should be left between the Rotor, hub caps, and supports to reduce friction. Rubber band size affects rotor and rod placement along supports for different applications. Additional components like gear trains can be attached for varying outputs.
