Doctor Who Iphone 6 case - dual extrusion

My niece got an Iphone 6 this Christmas and is a big Doctor Who fan
like me. So I created this Doctor Who inspired Iphone 6 case. I have a 3d printer with dual
extruders so I made the doctor image a different color to make it pop.

For those of you who want to make the image and text stand out just
position it higher than the case base.
For those with one extruder I made an embossed version of this
case available here - http://www.thingiverse.com/thing:618822
