Hello everyone.
Im looking for ways to imporve the cooling of the extruded filament (top layer) and been scouting around on thingiverse and found some nice fan ducts.
But, all of them only cools the filament, and not the heat shields.
Dont they need some cooling to? I thought the fan small fan was for cooling them, while the top fan is for cooling the filament.

Best regards, Andreas

Hi,

[quote=“fridh”] I thought the fan small fan was for cooling them, while the top fan is for cooling the filament.[/quote]It’s the other way around. The top fan is for cooling the PEEK tubes and the smaller one is cooling (at least trying to) the print. You only need cooling to print PLA.

I see!
