  1. 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.

  3. 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.

  4. 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.
