I set out to build an extremely low cost RepStrap System that could be built completly without having a Rep(St)Rap already. This is what I have so far (picture links to bigger picture on flickr or you can download the full size file below)...
Knurled rod pinch wheel extruder
Well based on the designs of Forrest Higgs, Nophead and Zach Hoegen (spelling?, and he was the one that came up with the lasercut acrylic extruder on the makerbot site right? if not sorry to whoever did it!) I designed this. I will build a prototype soon
