This is a remix of one of the designs from GoPro Hero Camera Mount" by benglish.
I extended the length of the mount, so that another strap can be added to hold the mount in position, when it is fitted to your wrist while scuba diving.
The other strap could be from a wrist mount dive computer or compass.
I made this because I found that the original mount held by one strap tended to slip around my wrist.
With the extension, I hope that the additional strap will help to keep the mount in position for the length of the dive.

Printed with a high infill %, it's going to go deep under water and I don't want it to break too quickly.
I needed to file under the GoPro mount arms a little to get the mounting leg to fit.
Other than that, no significant post processing, aside from removing supports.
I used 3D Builder in Windows 10 to create this.
I copied the original mount, added it on, trimmed the GoPro mounts off.
Then I stretched the new bit in one dimension.
I subtracted a couple of blocks to create the cutouts.
Then I merged the lot to get the final design.
