I'll try to remember to upload a real photo when I've painted one.
This isn't the same icon as some wargames use, it's a mixed up thing, but it's still fun. Sorry, we wanted horns and a lower jaw. If you like it, go for it. If not, don't bother using it :) The tiniest sizes are hard to print.
I uploaded lots of different sizes so that the thickness might be printable. You can also shove them into other models to add detail. The 40mm one looks really nice, but I'm not sure what its used for!
Completely unrelated, but check out my Lego R2-D2: http://L3-G0.blogspot.com (working, full sized, that's why we bought a 3D printer).
