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, not imported from another CAD system.

This means that the model should have no overlaps (use rtcheck and/or g_qa gqa commands to verify there are no overlaps) and will probably consist of five or more regions (one for each gear and the casing). Create one top-level combination to group your regions.
