After looking for a while for a 1.75mm, I decided to design my own.
First I tried some Direct Drive extruders available in the web..
The need for a motor fan for low Tg materials like PLA bored me.
The low resolution (low steps / mm) is not something pleasant to me..
And huge gap between the pinion and the filament output duct makes it difficult to push flexible filaments like Nylon..
So I came up with a geared 4:1 extruder, that has been working fine with many 1.75mm filaments, like ABS, PLA, Nylon and PET.
It is simple to assembly and low hardware parts count. Just download the correct extruder for your hotend, gears and Idler. Check Assembly Instructions for further information.
If you need the extruder for another hotend and/or hobbed bolt/pinion diameter, let me know on comments bellow.
