GoPro wrist mount...

From this...

To this...

I decided to use a Velcro strap we had lying around at home and Using the mounting plate in the GoPro box to make my own GoPro wrist mount.

I started by cutting the plastic mounting plate down and drilling four holes for cable ties...

Some sanding to tidy it up and get rid of any burrs, then threaded the cable ties through.

I used some double sided padded tape to cushion the back and then secured it to the strap with the cable ties...

It can be used with the flat and angled brackets...

The only issue maybe the strap is a bit big for my skinny wrists! Should be able to try it out tomorrow.
