3DPrinted Cover for Iphone 5 , design version 1

Here is a cover I specificaly designed to be 3DPrinted with the Fablab printer, in the objective to be very light in material use.

To do so I imagined an open-structure that gives in addition a flexibility feature that is interesting for the phase of plug/unplug to the phone.

This Design includes also a customisable area to receive any king of graphics, could also be a typo of course, I need some help to go further an propose a configurable model.

What did I used ? CATIA 2013x, Imagine & Shape + GSD.
