Model a planetary gear set in 3D using BRL-CAD

completed by: Raptor

mentors: Kesha Shah, Jacob B

This task involves modeling a planetary gear set in BRL-CAD. The gear set should be accurately modeled in such a way that it can be printed using a 3D printer. This means that the model should have no overlaps (use rtcheck and/or g_qa gqa commands to verify) and will probably consist of five or more regions (one for each planetary gear and the casing). Create one top-level combination to group your regions.

The output of this task would be a rendered image and .g file of the model.
