Phone Clamp for gopro mount

Simple but effective 3d printed spring loaded phone holder. Requires two self tapping screws width 3.5mm, I used a screw length of 16mm.

If you do not have springs laying around rubber bands would do just as good. Simply add more rubber bands for more tension.

NOTE: This will NOT keep your phone secured during movement. Only intended for mounting your phone stationary. Adding a few rounds of electrical tape on the clamping ends does increase a lot!
