man, I made all these models, made the drawings, and then never got around to posting them. sorry guys, i've been busy/apathetic/*insert other excuses here*.

feel free to check over the drawings, some dimensions may be incorrect or there may be other mistakes, so I'll update them as need be. I also modified some of the parts to make the extruder easier to make with a mill and lathe.
Disclaimer: keep in mind that these drawings are really really lazily done. I left off a lot of things that should be there, like datums and geometric tolerances. in fact, I pretty much left everything without tolerances. I assumed this would be fine because the tolerances are rather loose to begin with, and the drawings aren't going to a vendor or anything like that anyway.
