SOTC Model Cleanup Test

This is a model that I would like to use to get feedback on model cleanup techniques. Being designed for animation rather than 3d printing, there are bunches of protruding triangles, self-intersecting triangles, possibly some faces oriented the wrong way, maybe holes too.

Share your techniques to allow mesh-newbies to making this (and other objects) printable.

For fun, I tried slicing and printing it, but skeinforge was complaining all the way. It actually printed fairly well considering -
