iPhone 7 and 7Plus Cases - Ultra Thin Rigid

Update 27 Jun 2019 I have redesigned these cases. My new designs are at https://www.thingiverse.com/thing:3716349

This case is very thin, with smooth contours. I was careful to make sure that the openings for the phone buttons and camera were precisely located. The vertical and horizontal curve profiles are very close to apple specs.

I tried other designs from various sites, and was disappointed by poor fit, hole mis-alignment, and unnecessarily sharp edges.
