Isn't this a peek fan? A hot end fan would be pointing at the nozzle.

Hi Francisco

Hmm, interesting thought. Probably yes. This mount was designed well back in times, when it wasn't common knowledge to cool the PEEK part, so I didn't know how to name it. Today I would use a funnel which wraps around the PEEK tube with a smaller fan which doesn't collide with the delta arms, so this part of the hotend gets cooled as efficient as possible. But since I moved on to a watercooled hotend a couple of years ago, I don't have to bother with this fan anymore. By the way, you never want to point a fan directly at the nozzle in order to keep the nozzle temperature constant. That's the trickiest part, to get airflow directly to the printing part as close to the nozzle as possible, but not to the nozzle.


Just to add a warning here - make sure you don't mount it inside of one of the sets of arms - depending on the angle you make knock the arm against the fan!

Simple, very useful. Thanks for posting!
