This is a light switch cover I made for my girlfriends new apartment.  I used this thing as the base and added a owl image that my girlfriend found.  To print this, you will need supports, they don't need to be too dense.  This print was actually the first time I used a multiple process print using Simplify3D.  The bottom (black part) was at a higher speed, extruder height, etc., then for the actual owl (white) I used a much slower printing speed with a higher resolution.  To get the two colors I paused the print at the layer in which the owl was started and changed the filament.  Then gave it an acetone vapor bath to smooth things out a bit.

Note: I just held it up to another light switch and one of the two screw holes don't line up, so I'll rescale it and post another version.
