Galaxy S7 Edge tripod mount

A simple tripod mount for my S7 Edge (and Spigen case) utilising parts I already had as much as possible ... though I had to invest in some 1/4" 20 UNC nuts for the tripod mounting.

This is my first design using 3D CAD (I still have much to learn!) and produced with my Ender and I'm pretty chuffed with the result but any tips for improvement will be gratefully received :-)
