If you have problems with efficient nozzle cooling, this is a good choice to replace the OEM part. Fits perfectly, thanks to the source model. I modified only the duct layout into a straight, focused oval tube, facing directly to the printing zone. Great help when using support-less air printing :)
- reinforced screw holes for secure tightening
- simplified positioning pins
- optimised wall thickness for faster printing
- lower angle blow tube (-10°) for more efficient print-zone cooling (insted of cooling the noozle)
PLA duct may melt and deform during use, due to close position to the nozzle.
