ThunderPeel, I didn't get too far trying to find the .cmp for every model (~100/500) but did get most of the main characters. Partial list
It's probably worth asking one of the Residual guys where this information is stored because presumably they must know to have gotten it working.
wiplash, I had a look at shapeways website and it looks pretty cool. I'll put up some Blender 3d files with most of the main characters.
I also saw there were some tutorials on their website for using Blender and the adjustments you will need to make to the models, such as joining all the pieces into one mesh, optionally hollowing them out if you want them to be cheaper etc.
