Downloadable 3D Printable Bumper for the iPhone 5. As per Apple's dimensions and we have checked the corners on the iPhone 5 against an existing case and it fits perfectly. You can download this file to customize and 3D Print for yourself. Sides and back have 1.4mm wall thickness so you can emboss or engrave. I have restricted the materials to our Nylon range as they are best suited for iPhone cases.
