FairCase4: Ốp lưng TPU cho Fairphone 4

My old PLA case kept getting damaged. The layers would separate if it got snagged on my pocket, or crack if it bumped too hard against my desk, so I treated this as an excuse to get into TPU filaments, and designed a case that would fit fit more snugly and (hopefully) survive all those daily bumps and bangs.

After a couple of iterations, it's now doing everything I wanted, so maybe it will work for you too. (I've also included the OpenSCAD file so you can make your own adjustments.)

Print Settings: I printed mine in Overture TPU (95A) with 3 perimeters and 100% infill at 0.2mm layers with a 0.4 mm nozzle. 

I was able to print mine without supports, lying flat on its back, but I was nervous the whole time. Saner folks might want to throw a few supports in there - especially under those button cutouts on the side.
