Description
I really wanted one of Iwo's ducted cooling fan ( thingiverse.com/thing:5756 ), but only had a 40mm fan, so I printed his thing, then made an adapter ring to fit my junk box 40mm fan.

You really need a stepper extruder to kill the threading, and that would be the single best upgrade I made to my system, but the fan is great for solidifying the extruded plastic, particularly PLA. I found that just slowing down the time it took to print a layer created problems with the PLA melting up the extruder stem (so much so that I put a ducted fan there too).
So hows the performance? Help in the tip cooling? No more threading?
You're welcome. I'm constantly amazed at what other people invent.

Instructions
Print Iwo's ducted cooling fan thingiverse.com/thing:5756 then print one of these adaptor plates. It just presses into the top of Iwo's design. You could drop a little acetone onto the join to glue it, but I haven't found the need. I have found a little strip of double sided tape is necessary to keep the whole duct in place on the build platform (can be seen in the photos through the bottom).

Thank you for the adapter, for some reason, I don't think I would have thought of this. ;)
