The two sides of the coin were handled separately. Pictures were taken outside on a bright overcast day without visible shadows. A Canon G9 camera was used and the pictures were digitized with 123D Catch. The two halves were joined together with openSCAD.
Print time on a Replicator was about 80 minutes. The model was printed directly on the build platform with 5 percent infill and 3 shells.
