These are files to 3D print. It needs to be printed in TPU or other flexible material to get the iphone inside the case easily. The case was printed 0.2mm resolution with 0.4mm nozzle. It has some thicker walls in the edges for extra protection.
I also made a case cover. I used dual extruder with black and white Tpu, same nozzle and resolution. I used supports where the camera protection is.
There is a case cover without a design to be printed with only one color. It also need supports for the camera protector.
