Introduction
Printed in polycarbonate and used the case for several months on my iPhone SE gen 2. Fits perfectly and no cracks have developed. It was challenging to design a case that is very slim, yet strong enough to drop without cracking. This design is the result of many iterations.
Printing and processing
Print with 100% infill.
I used Polymaker PolyMax PC filament.
Supports are not needed. The model has a tapered edge reducing overhang of the rounded outer edge to improve printability. The taper can be sanded off after printing.
A textured build plate is recommended as it gives a grip friendly texture and hides imperfections in the back of the case.
Sanding the edges with a 180 grit sandpaper gives a nice and smooth texture!
Installing case
Slide the phone all the way into the top of the case.
Snap on bottom right corner.

Design features
Edges protrude 0.8 mm above screen. For use with a glass screen protector, I suggest editing the CAD model to protrude the front edges further.
Back is thin (1.45 mm) for enough flexibility to snap the case onto phone. Edges are thicker (2.1 mm, ~5 lines with 0.4 mm nozzle) for higher strength.
Bottom edge (by cable socket) is rounded and (almost) flush to the phone to ensure a comfortable grip.
Other notes
I have tried using several kinds of filament and had the best results with polycarbonate. Its high toughness and layer adhesion gives sufficient strength to make a thin and durable case. In previous iterations of the model where the fit was slightly too tight, the edges would develop stress cracks over time. This seems like a peculiarity of polycarbonate, as most other filaments would deform rather than cracking. I resolved this by dialing in the model dimensions properly.
Using basic PLA the case was too brittle. The PETG filaments I have tried were uncomfortable to grip. ABS, ASA, or hard TPU could work well, but I have not tried any of them. Please post a make and report your results if you do 😃
