I wanted to make a nice, compact extruder for 3mm filament, and direct drive extruders just don't have enough torque. So I designed this compact, planetary geared bowden extruder with a roughly 5:1 gear ratio (similar to a wade extruder) but far more compact. There is a quick release handle to easily change filaments, and M3 mounting holes which I use to mount on a kossel.
The planetary gears are based on Emmet's gear bearing and print assembled, although the rest of the extruder needs assembly.
