Makerbot Replicator 2 Filament Feeder

So we've been having a TON of problems with our feeder recently and so I'm redesigning the thing.

LIKE IT SAYS AT THE TOP OF THE PAGE THIS IS A WORK IN PROGRESS! GIVE ME FEEDBACK IN THE COMMENTS!

I haven't tested the newest version yet (I'm at take six right now) but I will have it within the next day or so.

Also, I'm not entirely sure that it won't just melt if you print it with ABS or PLA plastic... I plan to try it with ABS but that doesn't change the fact that this part is right on top of the heated bar of the extruder...
