Materials needed:
3x7x3 Bearings for the planetgears
5x16x5 Bearing for the cover
M3x14mm screws and nuts for the planetgears
M3x20mm screws for the whole assembly
I printed it at 40mm/s and with a horizontal expantion of -0.1mm
The author remixed this model.
I used the best parts of both models to make it as small and sturdy as possible.
