Tesoro Sand Shark Armrest

thingiverse

Velcro strap only lasts a few hours in the water before coming loose, This arm rest replaces the included arm rest that you attach to your arm with a stick-on velcro strap. It is loose enough that it will allow the metal detector to hang from your arm while you manipulate your scoop. I made it from ABS and put it in an acetone vapor bath overnight to strengthen and smooth it.
