Single Piece Motor Mount

A simple one piece motor mount for 12mm OD Booms. Added relief for SHCS's to mount motor. Anti-rotation hole for M3 scew.

Update 4/28/2016: Motor Mount Rev4 - anti-rotation hole changed to 3.1mm in model to remove slop, should fit an M3 screw now. Added jig for drilling boom.

Update 6/4/2016: Be careful not to over-tighten the anti-rotation screw nut. It will crack the motor mount, which will lead to failure during flight. I found this out myself while doing a hard climb out.
