About this 3D model

This planetary gearbox was designed to provide a large reduction ratio in a relative small design. The bearing balls I used are 3.2 mm in diameter. After my harmonic drive prototype I wanted something smaller that could house a high reduction ratio into a smaller space. Also I wanted to get rid of the flexible parts. The gearbox runs nice and smoothly. If you have any comments or if you need any custom parts for this thing (e.g. motor mount or shaft mount), please let me know! Thanks for viewing/watching!
