Nema 11 Extruder

thingiverse

This extruder is designed to work seamlessly with a mk7 pulley, a nema11 stepper with 5:1 gear ratio, and the E3d hotend or any style of j-head. Standard bolt mounting holes are used, spaced 50mm apart. Additionally, I've included a 90°mount, allowing you to attach a fan as well. The mount features built-in partial supports.
