Use this extruder with the 50:1 motor offered by 2engineers. The most recent versions of EiNSTeiN do not support this motor making the old one a little hard to find for some people. Here is the February 15th version, which is the latest that support the 50:1 motor. The new version of the 50:1 motor has an extra steel gear and is proving very strong for me thus far.

it is intended for 3mm yes. I used a standard mk7 drive gear. I am not really sure on the other measurements but it is intended as a jhead mount. this should be the correct scad file:


(1) Is this designed to work with 3mm filament?

(2) What is the outer diameter of the filament drive gear you're using?

(3) What is the height of the groove (bottom, narrower) part on the mount?

I'm using a "Raptor" gear which has an effective 10.5mm diameter, so I want to make sure to align the filament holes properly.
