Side Chassis Motor Mount

This is for a RoombaPi that my daughters and I are developing.

The mount is designed to sit on top of the sweeper (See above) and hold motors from an RC car. This is the first part I designed, and have been modifying it to fit out needs for the RoombaPi. You are welcome to use this, edit this, etc.
