I have had an idea floating around for increaseing the ammount of printed plastic parts in the reprap, It would use a printed plastic rack and pinion to move each of the axis.Im not sure if it would work, but I wanted to share the idea and get peoples opinions of it. The possible flaws and the positive aspects of it? It uses a bowden extruder so this should improve printing quality. The steppers are connected directly to the gear and the stainless steel bars are clamped in place using printed plastic bar clamps.The frame is wooden, but held together using angled printed plastic parts. Anyway ive attached an IGIS of the model, this is purely for explanation purposes, sizes gears and parts are not correctly sized. position of parts are not even in the exact place.
