This extruder can be connected to Hangprinter by tobblelobb.
So it feels better for me because i am used to mk8 and e3d v6 extruders.
You can attach this extruder to Hang printer by just drill some holes on baseplate.
It can be connected to any other printer or even cnc machine becaue it has zero clearance on top but you can still depress filament with lever towards you.
All other parts (bearings, screws) you can source from existing mk8 extruder or just take 3mm screws.
