This is my WIP open source solution for remote direct drive extruders. While I am prototyping in PLA, more robust materials would be better suited. The files for shafts have hexagonal material near the botom, solely to promote adhesion. you will need a 5mm shaft/bolt shaped like a nema 17 shaft to attach to the spur gear and for mounting te drive gear. I will update the files and create a comprehensive BOM as I go. Thank you for taking a look!
gears and shafts should be printed at a higher resolution and/or higher infill. Print one of each file.
