Workbench dual extrusion hotend base. (not for the Apprentice!)
thingiverse
So as I'm upgrading to a cable drag chain, I decided to disassemble the whole hotend. It was a no-brainer decision - why wait? While I had it apart, I quickly fabricated this model so that if my OEM part ever broke, I'd have a backup to print at my buddy's printer. I haven't printed this yet. By the looks of the OEM piece, it appears to have been printed on without the protrusions. Eventually, I may get around to refining this design and positioning it correctly for printing, but first things first - I need to finish upgrading that drag chain! This model is fairly complete, but it needs some fine-tuning. Unfortunately, I don't have time to clean it up completely right now.
