Raspberry Pi Camera CCD Lens gopro case

I wasn't able to find what I considered to be a 'good' gopro mount for a raspberry pi camera (v1) board that would accept an M12 CCD style lens mount separately from the housing.

I've had numerous issues over the last year with integrated mounts (where the M12 is part of the housing) getting out of focus due to the housing warping. I've found the independent M12 mounts work better in this regard, but there aren't too many housing I could find that play nicely with them, and I couldn't find one that was gopro mount compatible in a manner that made sense.

Here's what I've come up with.

Case:
Print the top and the bottom, in a z-layer height that whole numbers divide evenly into. 0.2 or 0.1 work very well, 0.15 -- not so much.

Print the M12 mount with 0.1mm layers (or smaller) for the M12 threads to work.

Assembly:
Use two M2x4 cap head screws to secure the M12 mount to the board. (you'll need to remove the lens from your Rapsberry Pi first.... but you knew that, right?

Use two M2x6 (or 8) cap head screws through the back of the case. The board will be held in place by the upper screws, and sandwiches snugly between the front and back case to keep it stable around it's perimeter as well.
