GoPro Smartphone Clamp

I needed a smartphone mount for my car. I had a GoPro Suction Cup Mount lying around so I build a smartphone clamp for it.
You can choose between a horizontal or a vertical GoPro mount.
The clamp should work for 4,5", 5,0" and 5,5" Smarthones. I do not have a 6" Smartphone for testing but it should work too.
You need two M4 Screws and two M4 Nuts to assemble the clamp.

Have fun!
