it would move the extruder tip up so the belts hit the frame with the nozzle another 20mm higher or so. It would cool the motor a bit while cooling the insulator and the part
The trick is making the volume right so there is no back pressure.

Yeah, those little fans can't handle any back pressure at all! I was thinking of finding the little squirrel cage blowers that they are putting on some cooling fans.

The flow will be figured going through the riser block around the hot end, any volume that is needed to make up the difference will be dumped down to the tip to cool the print.

interesting…should work well if you can get the duct just right 😉

I tend to use yellow to signify a different kind of flow… 😛

You'll have to keep it constant open cross section throughout the ducting then. Not impossible, just a little tricky. May take a few iterations.

I think PC squirrel cage fans are your best bet for an affordable, known value unit. AS&S appears to have one, but it's only 28CFM at 24VDC

I do have this 3d printer, you know? I could print my own cage that mounts on an existing fan motor hub.

You can try. I don't have a design for a squirrel cage blower sitting around.
