Samsung S4 Case (For Flexible Material)

I couldn't find any simple and elegant cases for my s4 so I made this one and like to share it with you!

This is intended for flexible material as I have created the inside edges that protrude inwards to grab the phone pretty much all around the case.

Should work just as fine with any
flexible material, TPU is the hardest ive worked with and came it fine.

I also have included two other revisions with different size fillets on the outside bottom edge for comfort or for easy printing
