cOssel Bowden Extruder - Geared Stepper - v2
thingiverse
A compact bowden-type extruder designed as a seamless replacement for popular airtripper v3 and bsp designs, tailored specifically to accommodate geared stepper motors. Integrated geared steppers demand a different mounting pattern than traditional NEMA 17 motors. A commonly used geared stepper motor in the RepRap community is the Phidgets 5.18:1 motor, which I have utilized as a reference in this design. The motor mounting holes are closer together on geared steppers compared to traditional motors, forcing the extruder body to be more compact than its non-geared counterparts. Only a 1.75mm filament is currently supported, but if there is sufficient interest, I can make available a version compatible with 3mm filament as well. Simply drilling out the guide holes allows for easy adaptation.
