After many weeks of designing, I have finally finished prototyping my iPhone 5 bumper. This bumper is the first of its kind in that, it is too small for the iPhone! how will it work you say? Simply heat the bumper case just a little and slip it on. As it cools, the case will become tighter on the phone causing it to be more anti-fall-off-able! This will allow the case to be more resistant to heat expansion and the possibility of it coming loose.
