60mm fan to flex hose
Description
The hose just screws into the adapter. The fan bolts to the adapter using M3x16 bolts and M3 nuts.
Instructions
search.digikey.com/scripts/DkSearch/dksus.dll?keywords=603-1162-ND
12000 RPM, 2.129 in H2O (530.3 Pa) static pressure
The hose I used is:

Even with 20 feet of hose, the fan moves a fair bit of air.
The fan is surprisingly quiet when connected to these adapters and the hose.

nice thing! Did you match the fan for this size of tubing, or is it just what you had on hand? Looking at the fan I get the impression that the swept area of the fan is much smaller than the area of the tube. That might not be a bad thing, your airflow in the tube will be slower than through the fan.
I had a 60mm fan on hand I planned to use.
The tubing just seemed "about right", big enough to move some air, quite flexible, and small enough to sneak through an open window.
I originally had a lower performance fan (from my big drawer of fans), but the airflow would drop really bad when the shroud and hose was connected. I sorted all th
e Digi-Key fans by static pressure and noise and this is the one that came out on top.
So I am basically just shooting from the hip.

where can i buy these ?
Just grab the STL and print one on your 3d printer :)
You can have ShapeWays ( http://www.shapeways.com/ ) or another shop ( http://www.alphaprototypes.com ) do it $$ or see if you can find someone who has a printer to print one for you.
