About this 3D model

I originally drew this up for the Iphone case but with a back plate for ease of mounting. This has the back plate removed. It is two parts and so if you have two extruders, there is no need to change filament half way through. I printed it scaled up to 100mm width at 0.2mm layer height, 2 shells, 10% infill in ABS with no raft or support.
