Case/Cover for Shargeek 100/Storm2 Power bank (STM2-2)

This is my cover for the Shargeek 100/Storm2 Power bank (Model: STM2-2) The first one is a full cover that has no design, except for a hole for the screen and the button underneath it. The second and third ones are "Wireframe Inspired" which means they have sharp angles and are designed with polygons in mind. The second one was printed and is an improved version of the last one.

I'll make any (reasonable) changes/improvements you have, just contact me.
