Samsung Galaxy S6 case, stiff, light

The original design was intended for flexible filament. It would crack if printed in PLA when mounting on the phone. I made some extra cut-outs so that PLA could flex enough to mount on the phone without cracking.

Since this back is thinner than the camera protrusion, there is also a design for a protective camera ring which can be glued to the back.

After printing this for my new phone, I found http://www.thingiverse.com/thing:814007 which may also make a good starting point for my case. Revision "C" is my first design. The current revision, "D" uses the above template.

I have added an (optional) front face protector. I super-glued some overhead transparency over the honeycomb for extra protection. You can attach the two sides with some cloth for a hinge to make a book-like protector.
