CAD Design changes

iPhone 5 Bummpies:  larger radius and Now with no under-cuts

We increased the external radius on the top and bottom edges...it just feels better and is very similar to the iPhone 4(s) Bummpie radius (Image 1).

The PSA relief on the inside of the Bummpie had a angle that was perpendicular to the curve, but this caused an undercut and is not suitable for injection molding.  Simple modification to the CAD file solved the problem (thanks Protomold for verifying the design)! (Image 2)
