I came across this instructable by goshrant from 2013 that shows how to make a neat zip-tie strap for a GoPro camera that can be tied around things at shoot locations. I thought it was a neat idea, but never made one because I didn't like the idea of littering the countryside with discarded nylon straps (when things are happening quickly, its easy to take shortcuts and rationalize about it later).
After facing situations where one of these would have been handy, I got to thinking and came up with this velcro variation.
Step 1: Choose Your Materials
You can certainly 3D print a mount as goshrant did, or cut up an old credit card as I've seen others do. I went another direction and came up with an old mouse pad with a stiff top surface, backed by dense closed cell foam.
If you decide to use a mouse pad, trace around the outline of one of your adhesive mounts and cut it out. It pays to wash this piece thoroughly to get all the grease and dirt out of it.
You'll also need a set of velcro straps. These can be found in big box stores, but I ordered mine online. These straps are handy for keeping tripods closed, wrapping up chest mounts, keeping stabilizers secure, keeping small parts together and a lot more.
You'll also need your GoPro mount of choice. I didn't get photos of the mount I used, or the assembly, so I drew them up.
Step 2: Assembly
Lay a velcro strip side to side across the tape on the back and trace its outline. With a scalpel or razor knife, cut the tape away between the lines. This is where the velcro strip will go.
Remove the protective backing. Align and lay the FACE of the mouse pad onto the adhesive.
All that needs to be done is to thread a velcro strip through and try it out. If your wrists are small, a single strip should fit around them, providing a great vantage point for close-up action. The rubber on the backside helps to keep the mount from shifting when it's not on a level surface.
If larger things need to be circumnavigated, simply add the required number of velcro strips, end-to-end, forming a loop that can be easily adjusted for tightness and removed when the shoot is done.
