3d printed planetary gear with gear bearings connecting the carrier to the gear planets. This allows (potentially) for reduced frictional losses in comparison to sleeve bearing.

The design is a extension of Emmett Lalish’s innovative gear bearing and also uses his pin connectors V3 library

The gear ratio is written on the using HarlanDMii Write library


Print the carrier and the planetary gear separately and assemble.

The included gear.stl uses a 0.15mm tolerance which may or may not enough for your printer. It can be adjusted in the openscad source file.
