GoPro Mount Arms

Update: Uploaded v2 of swivel arm. Male has a thicker shaft and female should have more clamping resilience, for stronger fix.

I tried a few designs from here, but all of them where thin and did not tighten enough.
So i made my own!

There are 3 different lengths in straight and 90 degree rotation, and one set for full free 360 rotation. Bigger and specific lengths can be made on request.
