Quadcopter Mount Bracket Adapter

This is a quick and dirty quadcopter mounting bracket for attaching a power distribution board or a flight controller such as the CC3D to a larger set of mounting holes - in the case where you want to use holes on both sides. The hole spacing is based on an EMAX Nighthawk 250 although should be fairly generic as the controllers all seem to use much of the same form factor.

*Dimensions:*
Inner Hole Spacing = 30.5mm.
Outer Hole Spacing = 42mm.
Screw Diameter = 3.5mm (for material shrinkage),
