This is a remix of a remix of the Fairphone 4 rear cover. The Phone's original cover has a roughly 1mm protrusion around the camera, making it not sit flat on any surface. The remix added a full cover extrusion such that the cover has a flat surface. However that extrusion was done in a way that the phone would rest very uncomfortably in your hand.

This thing takes that remix and rounds the sharp corners in z-direction. It looks and feels much better than the previous version. If you wish to tinker with the scad file be aware that rendering the preview or the stl takes minutes, that includes just opening the scad file.

However, this makes it surprisingly hard to actually print, so follow the print instructions below precisely or you will likely print for your recycle pile. This thing requires AMS and two materials for best results!
