MM3 Extruder T Nut Retainer

thingiverse

I engineered this modification during my upgrade of my MendelMax into a 3.0 model. They developed a new extruder, which incorporates a T nut for adjusting tension on the spring. Unfortunately, the T nut can rapidly rotate all the way around. Consequently, I devised this part (highlighted in yellow in the photo) to prevent the T nut from rotating freely. This requires very little printing time, and it simply clicks into place.
