FT Mini Firewall for 13mm bolt pattern

The firewall included in most of the Flite Test kits did not fit the bolt pattern for the motors I had, so I designed one that did.

Edit 2/13/19 - I increased the height of the model from 1.5mm to 2mm, slightly thicker than the FT plywood firewall, to combat the part from softening when hot-gluing into place.
