Basic Motor Mount for 8.5mm Quadcopters

I needed a basic motor mount to use with my Picnic Quads carbon-fiber frame. This one is specifically calibrated for 8.5mm motors but may require some scaling to be a tight fit. I have included the source OpenSCAD file, so you can adjust that to generate a new STL file.

Update 2016-04-26: New files with better fit.
