A case for the iPhone 7. The two-print case is designed to be printed using PLA or ABS, both pieces slide smoothly into the phone without damaging or even touching the buttons nor the camera. The single print cases are made for flexible materials.
The one I made for my phone was printed in white PLA and Wood PLA having both pieces printed standing up and at .2mm layer height, 100% infill, but I think you could print it in any position and still get good results. Have in mind to be careful while removing the case from the phone if you use very brittle materials. I recommend printing slowly.
Some sanding may be needed for the two pieces to fit better or to have a nicer surface. You could also break the area between the side buttons and the screen if you find it difficult to press the buttons.
I've also added the SolidWorks version of the files in case you wish to modify them.
Feedback is appreciated.
I used a Robo 3D R1 Plus, PLA and Wood PLA.
