Note: I have uploaded a version 2 of this model. The new one sits closer to the top of the extruder body but is also narrower to provide better clearance at the filament input ports. I have enlarged the holes for the M3 screws that hold the fan and did not have to chase these with a drill bit on the new version.
It seems to me that the small motors run hot on the Quad head. This is an effort to control the excess heat. Print in PETG as it is in direct contact with the part of the head it is trying to cool.
Noctua 40mm fan used on this modification.
This fan mount fits into a pair of what appear to be accessory rail connectors on the quad head. I had to cut the color indicator decal out of the way but that was just two small slots in the sticker.
I should note that it sits tight against the motor cables that feed the back two motors (1& 2).
I also had to chase the screw holes with a 7/64 bit to fit M3 screws.
Please post comments on any issues or suggestions with the model.
