If you needed an extruder for your RepRap, how would you print one?
From the Schlaboratory, a remix of Greg Wade's accessible extruder, optimized for Shapeways' laser-sintered nylon, designed to feed a Lulzbot Budaschnozzle. http://www.lulzbot.com/?q=products/budaschnozzle-20-w-035mm-nozzle. Including the Schlab version of the Guidler, the idler with filament guide and handy thumb "schlever" for releasing pressure on filament.
Designed for 5/16" hobbed bolt
and M3 25mm for the guidler hinge
nut traps for size 4 mounting hardware on base.
