1.75mm 28BYJ-48 Universal Bowden Extruder 1.75/3mm filament v.1

This is a universal bowden extruder, due to the design it should work on both 1.75 and 3mm filament just fine though I have only tested on 1.75.

I have only tested on my custom 3d printer that uses the 28BYJ-48 Stepper Motors, so pretty much I haven't printed much past 15mm/second @ 0.2mm layer height. I suspect this extruder will probably not let you print much past 30mm/second @ 0.2mm layer heights

(sorry about the crummy picture, it is late at night, I will post a better set of picture
