small dc motor gearbox

thingiverse

This collection of parts and scripts makes it easy to build a simple gearbox. I created it mainly for reusing small and weak DC motors, which are typically too weak to be used with printed planetary gearboxes. As a result, they require very low-torque first stages. Changing gears is incredibly easy thanks to the two threaded rods that support the gearbox core. The motor holder, skate bearings holders, threaded rod holder, and plastic planetary gearbox for hex shaft are all part of this set. They make it possible to attach the gearbox to a housing using the threaded rod holder and provide power output via a hex shaft, such as for a peristaltic pump rotor. More elements may be added later. This gearbox serves well as a toy and can be used in any application requiring slow motion and high torque. Many of its components are copied from other people's designs; I've made sure to include all necessary credits, but if there's anything missing, please let me know.
