This fan and JHead mount was designed in OpenSCAD to try and cool the part when printing fast or thick PLA layers. It uses 3 30mm muffin fans and almost works. The airflow from the two part fans are rotational in the direction of the fan blades and end up directed both in front and behind the hotend nozzle. The 30mm PEEK fan is a bit large so it can block view of the part. I used that fan in reverse and pulled air from the PEEK instead of flowing on it.
It's being posted in the event anyone would like to modify and improve it.
