About this 3D model

Youtube link: http://youtu.be/m3w0liy-QJE 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 http://www.thingiverse.com/thing:53451 and also uses his pin connectors V3 library http://www.thingiverse.com/thing:33790. The gear ratio is written on the using HarlanDMii Write library http://www.thingiverse.com/thing:16193
