About this 3D model

I made this in OpenSCAD after seeing a similar one that one of my kids had. It's rendered at 0.66mm thick, and I print it at 0.33mm layer height. It's a pretty quick print and would probably make a great demo piece, too. The photos of the red bookmark show the older version, which had no nose. The blue one is the latest version. UPDATE 9/1/12: I fixed the centering on the slots, brought the eyes and hands in a little bit closer, and added a nose.
