Bowden geared extruder
thingiverse
Another bowden geared extruder for my Prusa Steel that uses a reliable hobbed socket bolt to prevent erosion of the 3mm filament from occurring in the first place. The original file can be accessed here: http://www.thingiverse.com/thing:60531. I have employed the common Gregs Wade extruder gears for this design. Make sure to verify the size of the tube connector hole before printing this thing. Instructions This video motivated me to build a hobbed bolt: https://www.youtube.com/watch?v=gLP_OmY7iTY
