DPRG,

While dreaming about robots this morning I drew up a 3D CAD model
of the vaunted Pittman GM8712 Gearmotor.  I realize that drawing it
yourself can be most of the fun, but in case someone might find it
useful I put JPEG, R14 DXF, and R14 DWG files online as:

The 2.5" x 3" motor mounts for this are in the same directory:
