Remix of the Adafruit "Light Ring" module includes mounting hole/post bits.

This is a remix of the Adafruit "Light Ring" model used on the [Camera Light Ring](https://learn.adafruit.com/3d-printed-camera-led-ring).
I wanted positive mounting posts to more securely seat the diffuser ring over top of the diffuser that holds the NeoPixel ring, so I made this. In test-prints it fit together pretty well, but as always, YMMV, esp. when printing w/ PLA.

Enjoy!
