Gopro diving handle

My first design of a gopro mount for diving (untested). You can attach it to the straps of your harnas.
It sticks on the magnets. When you want a closer view, you can grab it and point it at the subject you want. Once done, just attach it to the magnets again.

Parts needed:
Magnet (https://www.supermagnete.be/magneten-om-te-schroeven/blokmagneet-20-x-20-x-4mm_CS-Q-20-20-04-N)

2x inox screw M4x10
2x inox screw M4x20
