One of the motor controllers commonly used by FIRST robotics teams is the Jaguar. The solid model supplied in the KOP files is missing part of the base. I modified the model in Creo, student edition, which is available free for FIRST teams. I exported the part as a STEP file so it can be imported into other CAD packages.

We made dummy Jaguars to replace the real ones in some of our robots which are on display in the Virginia Air and Space Center, in Hampton, VA.
