Cube 3 Extruder Hub (Cartridge replacement)

I've had something like where you ended up, yes.

This makes for a nice fitting-less adapter...

Edit: This was easy to incorporate in place of the fitting at a lower level.
Turns out the #8-32 nut is bigger than the metric M4 nut so this should be easy to incorporate.
Got a print running with this and it is solid as a rock!
