Skeleton frame for GoPro-like cameras

I tested with the "Campark Xtreme i+ UHD 4K" off Amazon, but it may fit other generic GoPro-type cameras out there.

The Campark Xtreme i+ UHD 4K camera I bought came with a waterproof case and many mount arms but no other camera holders / cases. The waterproof case is heavy and bulky, so I wanted a frame I could use when not planning on getting the camera wet.
