There has only been one other case on here so far for the s5 and it's very bulky, so I made to be printed with flexible filament. Works well with the makerbot filament. Buttons don't press as good as I want. I'm working on making them better by messing with their chamfers. Fits tight, so it probably won't work well with normal filaments.
Printed .15mm height, 3 shells. Has built-in cutaway supports
