Don't think much people have that hotend but figure I should put it out there, the extruder screw hole no longer fits Sherpa/HGX or sailfin extruders and will only fits the orbiter V2.
This is for the 3Dsway's CH-C volcano hotend with screw on heatsink, check picture to see what it looks like.
The author remixed this model.
Different hotend and no longer fits Sherpa extruders and will only fits the orbiter V2
