Direct drive extruder for K8200 and E3D hotend.

This is a direct drive extruder for a round gearbox. This was for me a test print to see how the part turned out. I finally milled this out of aluminium. It is a great extruder for the E3D hotend. It is a direct fir for the K8200 printer.

I have no idea if this one will work if it is from plastic.
Especially the bearing holder could be to weak.
