Don't laugh but some friends of mine are starting to work on a xmas show. They asked me if i could make some 3d moose and deer to use for their decoration. i found this thing online and would wonder if somebody has something like that in dxf. (by the way I like all the 3d cardb puzzles they have at the cardb safari)
I remember seeing that image over at Phlatprinter. Check out the gallery and ask them.
I also thought the Google Sketchup Slicer program could help.
