Pinch Wheel Extruder Prototype

I had a great idea for a new, drastically simplified extruder design for RepRap. I decided to spend a day on it, and if it proved fruitful, then I’d pursue it more. Thank god for the laser cutter at NYCR, because I had a working prototype made up in an hour. After that, it was fairly simple to design a nice layered housing for it and make it into a reliable little beast.

There is a much more detailed post on the RepRap blog, you can look at my flickr set, or check out the design on Thingiverse.

    How were you able to have such clean cut pieces of Plexi-Glass? I have tried with multiple cutting tools and they never give that clear cut look.
