A case for the NOIR camera and Bright Pi board, for use with Austin George's Ender 3 Raspberry Pi Camera Mount

This was designed based on the header being soldered on the opposite side from the LED's

There is an arrow marking where the ground pin should be but since it is possible to solder things the other way around, pay attention to where the ground pin is before putting the boards in the case.

The mounting arm seems long until you attach the cable for the Bright Pi, then you need the length to be able to tilt the camera back.

There is a bit of an edge on the back and a corresponding recess in the body, so the back should snap in place.
