Xiaomi Mi Max 1 backcover

My first work that I decided to publish.

Just a simple back-plate cover for my Xiaomi mi max 1 Helium, with a simple cross design to minimize the material used.

This is the second run, and I'm not totally ok with it: I would like to extend the edges past the screen a little more and to try a better material, like ABS, but the other dimensions are spot on.

I decided to include my Solidworks file: use it as you see fit! UPDATE: added a parasolid copy as asked by Paradelux
