Angled cooling fan
Can anyone tell me why this changed from vertical to angled on the latest version?
I wanted to add something and the angle is in the way. I'm trying to find out what the problem would be in going back to the original vertical setup.

Hi Trevor,
the 45 degree angled fan is reputed to provide better cooling air flow than the 90 degree angled fan.
I use 90 degree on my mk3 with mmu and don't seem to have cooling difficulties, however I don't use the standard part cooling fan duct... and I am not sure which alternative it is

Re: Angled cooling fan
I printed some parts from clear filament with the original cooling fan. Wasn't happy with the results. Later I installed the Mosquito hot end which has a different cooling fan implementation. On a whim I reprinted the parts and they came out fine. I mentioned this to a friend of mine. He ordered the same filament and printed the same parts with the new Prusa fan parts with the same results. He than installed a Mosquito hot end and printed with good results. His results verified mine. Seems cooling is a more complicated process than one would think.

Yes the air nozzle is a complicated but important component 😯
