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

You're welcome. I'm constantly amazed at what other people invent.

So hows the performance? Help in the tip cooling? No more threading?

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).
