Side mounted fan duct for a rostock effector.

My thermal break cold part is water cooled by a part I made myself but mywork piece fan cooling has been a bit poor with side fan only after I ditched my damaged previous hot end for an all metal replacement. Allow at least 40mm clearance from the underside of your effector to undersling this, that will give an air gap to flush the heat away from your print. I should mention that I use swivel joints on my effector and carriages, mounted to the outside attachments, this won't work if you are using the standard universal joints and forked bars.

Remember to shut your fan off for printing with nylon, PET-g etc.
