AD Neopixel Jewel Mount

Adapter for mounting a Neopixel Jewel inside a cylindrical holder, with standoffs. It is intended to work like a 45 RPM record adapter. The outer diameter is 36.5 mm to suit my application.

Edit 2016-05-08: I have uploaded the new revision of this part. It was rebuilt in Fusion 360 and in the process has been changed to have three arms instead of four. I have left the old OpenSCAD thumbnail to show the intended usage.
