Velcro strap wrist bracket for wearing mirrors and other gadgets

This is a remix of my F80 smartwatch wrist strap cradle. Someone suggested that it could be used to hold other things, like a small mirror, and that it would be nice if it could be mounted with a velcro strap, so here is a modified version that accepts a velcro strap up to 26 mm wide.

Also included is an insert that fits in the cradle. You can use this as a starting point for other things that you want to make both wearable but also easily detachable from your wrist at the same time. Of cours
