20x24mm Triangular Mount Pattern Adapters

Thing https://www.thingiverse.com/thing:3294137 from user mrath mounts a JeVois camera to a plate that provides a M4 20x24mm triangular mounting pattern. It was the inspiration for the mounting pattern used by these mounts.

This is a series of adapters that can convert things using a M4 20x24mm triangular mounting pattern to other types of mounts such as GoPro compatible and 1/4-20 tripod mounts in various orientations.

Note: I don't understand why there are black artifacts in the .stl preview pictures. They sliced and printed fine for me. They were created from fusion 360 with high resolution. I was happy to get previews to work at all here :).
