Rendered in "Red Shirt Red" & Gold, this design is an offshoot of my hobby design workshop logo.

I also rotated and centered the battery for better overall balance. The shell is 3mm thick and I have included threaded inserts and flush mount screws. The back is also tabbed to snap in place, securing the back with 2 M2x0.4x10 flush mount Hex drive screws.

I keep the SIM and SD card mounts closed to the outside, as these are typically infrequent access ports and can be changed by opening the back of the case up.

 UPDATE: The tabs on the phone rear were a bit weak, so I have widen them and increased the filet at the base. Also changed the split between the front and back. The holes around the headphone jacks were too thin and broke easily. The V2 versions hopefully won't have these problems.
