I have an Akaso Brave 7 LE action camera that came with mounting accessories. I mounted it to the side of my computer case on my desk, which is 4mm thick tempered glass, using the adhesive mount it came with.

It fell off after about 16 hours.

So I created this simple clip that accepts a hidden socket head cap screw (1/4-20 threads) and allows the camera to hang on a 4mm thick panel (glass in my case). The screw should pass through the hole with the head of the screw on the inside of the clip, embedded in the recess. The screw will lock into whatever 1/4-20 mounting accessories you have.

This isn't really just for Akaso cameras. Anything with 1/4-20 mounting should work.

Sketchup file is attached, as well as the STL.
