Hi all,

I just found the following thing:

This is a remix of an earlier Active cooling fan duct thing by the same creator. I just made this one, and it fits really nicely. The fan is tucked in a bit more, and the clips that attach it to the extruder carriage are well fit. I had to do a tiny bit of trimming, but this is a very nicely fit fan duct. I can feel the air coming out, and with my 12v fan, it appears to be fairly robust.

Cheers,

John
