Arducopter motor mount for A 2830 12 motor Free 3D print model

I recently wrecked my arducopter and am now trying to redesign/rebuild it. I modeled this piece in maya, using my own measurements, so it is not exact to the original, but should work just fine.

Print and attach to arducopter frame.. The screw holes are set at 3.5 mm, but may need some cleanup depending on your machine calibration.
