The file 'Compact Bowden Extruder (Geared Motor Version) For 1.75 Filament 3D Printer Model' is (stl,stp) file type, size is 6.0MB.
This is a variant of scarou's and 0110-M-P's Compact Bowden Extruder. It's been designed for use with 1.75mm filament and a Nema 17 Planetary Geared Motor with a 8mm bore hobbed drive gear.
Tolerances are very tight, so I don't know if this design can work with a different hobbed gear and/or a different geared stepper motor.
Here is the link to the ones I've used:
STEP files are included, so feel free to modify the design as you please.
Added Body that fits the Rostock Max V2/V1. The distance between the mounting holes is the same as the EZstruder, so it works with the stock mounting bracket.
