Bigger motor mounts for Martian Rover

The motor mounts by RebBaza work for the Hobby King motors that he indicates in the source (I expect) but the motors that I ordered (http://www.ebay.co.uk/itm/252292792571) turned out to be slightly larger and wouldn't fit.

This is a compatible version of the motor mounts that fit the larger motor. The FreeCAD original is included as well as STL in case anyone wants to customise it further.
