Xperia Z5 Compact basic case

EDIT: 18/06/2016
In response to a comment, I've uploaded a thicker back - 0.5mm thicker than the original. I hope this will make those who were having difficulties happier? I also uploaded the original .blend file (not thick back) if anyone wants to redesign it in depth.

My own work-in progress design for a Z5 Compact case. Simple and pragmatic, needs supports for the power/volume/camera button openings.

Still a WIP until I make sure the phone can't really get loose of the case.

I printed my latest version in Polyflex, and it's just a tiny bit loose. But the rubbery texture makes sure it doesn't slip off too easily.
