Based on a model made by my bud Chris Webber, which can be found here: http://mediagoblin.com/u/cwebber/m/fear-of-flight/
Psycho is a character from "The Misadventures of Okk", by Brian Raddatz.
Note that the original blend is rigged, so you can re-pose the model to your heart's content.
1) Pose the model to your liking.
2) Export stl files for the eyes, body, and mouth; use the openscad script to combine them.
3) Reimport the combined stl in Blender (or anything else really), and rotate and resize the model for printing.
4) Export again, slice, and print.
When printing, I recommend using skeinforge's ability to add supports. With the way the model is presently angled, you should only need to have supports appear under it as apposed to everywhere.
