Battery powered belt driven planetary gear
thingiverse
Getting tired of fiddling with the planetary gear, I decided it was time to give it some real power. I started by attaching a belt wheel - fashioned from rubber bands carelessly discarded by my mailman on our street - and then added a sturdy motor mount and reliable battery holder. The new components are now firmly glued to the planetary gear. Unfortunately, the contacts on the battery holder weren't quite up to par, so I took matters into my own hands, using some durable copper wire and superglue to craft a more effective solution. https://youtu.be/M68yE7k13DI
