head bobbing mechanism pulley gear & body bottom cover

thingiverse

I'm designing a pulley gear that I need to install on a worn-out animatronic, which apparently has some badly deteriorated gears. The design should be versatile enough to work with any belt-driven head bobber, from dancing gorillas to generic animatronics from the early 2000s onwards. Additionally, as the repaired animatronic had an extra unused battery compartment for a second unit, I've created a simple cover to replace it and utilize the space for another personal project or repair.
