this is a compleat replacement for the Cetus3D Cooler/fan duct to use a 60mm fan.
be sure to use 5v fans :)
there are one Version without support (so you need to add support)
and another Version with support (with the _s ) (Cetus software just adds a little to mutch support for my taste :) )
if you print the version with support pleas make sure to use 0,2mm layerhight
i use a Noctua 60mm x 25mm 5v fan that is very quiet - the pressure is a bit low but like you see on the bridge test picture (50mm distance) it works fine :)
i uploded a new version that allows to block the cooling on the printed part without altering the cooling of the cold end :) V5 has a slit were you can put the blocker in :)
