One of the requests was a tripod moutning point. I wasn’t sure how I was going to do this as I figured I would be machining it from scratch (denoted by the green plate at the base of the 3D pic in OP ). After some head scratching I got an idea. I have a couple of gopro style action cams. They come with more accessories than I need /use. I picked out the one with the deepest hole. In the new host it is a press fit with some epoxy to help hold it.
