A quick render of 2 phone case options. The left one is more rugged/ drop proof with holes in the enlarged corners to allow harder materials like TPU to flex and reduce shock. The right one is a more basic case mirroring the shape of the iPhone.
Rugged TPU case idea with corner bumps and holes whick would allow more flex in TPU to reduce shock when falling on the corners of the phone.
