GoPro 3-3 Adapter

I needed a 3-3 adapter so I used Chardels' as a base since it was super clean to start with. Doubled the 3 prong side, created 3 lengths, and also tightened up the recess for the acorn nut so it holds the nut in place better. Lengths are 30, 40, 50mm center-to-center of the screw holes
