Battery powered belt driven planetary gear

thingiverse

Getting tired of playing with the planetary gear I decided it should be driven. I Started with the belt wheel (designed for the rubber bands the mail man leaves as litter in my street), and later added the motor mount and battery holder. The new parts are glued to the planetary gear. The contacts on the battery holder weren't really a success, so I used sturdy copper wire and superglue to make something that works. https://youtu.be/M68yE7k13DI
