3D model description

This remix from the Prusa i3 MK3 Extruder Stepper cooler by CG-Tech includes the C-1 part to be fixed directly on the Extruder piece. You can use the M3 bolt to attach it.

A tube also facilitates the introduction of the filament behind the duct fan.

I'm using this part with my PRUSA i3 MK3S because of PLA print failures while printing objects with many retractions inside an enclosure. PLA chewed up by extruder gear because of the high temperature of the extruder stepper motor .

The air flow is provided by a 40 mm Noctua NF A4X20 FLX Silent Fan; connected directly to the EINSY 24V output using a DC24V to 12V converter.
