QU-BD Extruder Modifications
thingiverse
The extruder mod is based on bdring's design, and we appreciate his contribution. It uses an Mk7-style drive gear with McMaster-Carr pn 6138k64 bearing (3/16" ID, 1/2" OD) and doesn't require sourcing any screws, which is a significant advantage. To assemble, simply push the bearing onto the printed shaft for a snug fit. The design positions the Mk7 style drive gear set screw away from the stepper motor to rest on the spindle flat, preventing slipping and reducing lever arm length. The cad file was adjusted for a specific spring, making it easier than searching for a new one. Thank you open source reprap community!
