This was captured from a SketchUp model found on the 3D Warehouse. Credit goes to saikindi for that model. I then scaled it down (quite) a bit in SketchUp to produce a model capable of fitting in my 3D printer, then imported it into Tinkercad to clean up the file further. I used Repetier as the printer controller and Slic3r to slice it, and had no issues with either software.
The 3D viewer doesn't give an accurate representation of how the model looks when printed. The model doesn't appear triangulated or full of polygons at all.
Because of the large footprint and low overall height I had significant peeling problems on my PLA/unheated glass bed/blue tape combination. Because of the sloping and pointiness of a couple of areas, the hollow/mesh function didn't extend to a couple of the corners, which I believe had played a large part in the peeling. Despite that, the detail was pretty good, so I'll tweak some settings in Repetier and see if I can't make mine come out a lot better
