Spur Gearbox (50:1)

thingiverse

This gearbox and motor case is designed for use with the RS-550 DC 6-24V motor from banggood. Number of parts required to print: Big gear - 2 Medium gear round shaft - 1 Medium gear square shaft - 1 Small gear to mount on motor - 1 Motor case - 1 Motor case cover - 1 Spacer (6) wide - 1 Spacer (23) wide - 1 Spacer (41) wide - 1 Spacer (6) - 1 Spacer (23) - 1 Gear axle square shaft - 3 Gear axle round shaft - 1 Gear axle nut - 4 Support structure (big or small) - 4 total Side wall (end side (this is where the threaded end of gear axles go)) - 1 Side wall (motor side (where the big end of gear axles go)) - 1 The gear axles (round and square shafts) should be scaled up by 1100% as indicated in their names. Gear axle nuts should be scaled up by 1250% as indicated in their names. Printing the specified number of each part and following the pictures closely, with a bit of experimentation, will make assembly relatively easy. This project is still a work in progress and will be updated eventually.
