How do I use a different print head on the Kobra Max?
This is a remix of DB42's fan duct found on Printables, and the CR-Touch spacer by TNick on Thingiverse:

The holes have been extended down by 8mm to allow for a Volcano heat block assembly to fit. Doing the bowl test shows very pinpoint airflow right onto the print surface.

All parts are in this model, just delete the optional fan cover if you do not want it, and choose between the threaded or brass insert back plate.
0.1~0.2 layer height. The models are already oriented in their print positions. You should only need supports on the bolt flange for the duct. Smaller layers will get you better threads.
