Will work with 3mm or 1.75 mm filament.
This is made of the same machined stainless steel (304) used in the previous extruder gear, with new dimensions to better fit the 5 mm shaft of the NEMA 17 used in the MK7, same effective diameter of 10.56 mm.
If you need a replacement gear, or you're designing your own custom project, this is the part!
