Fan Duct under 3 pro

thingiverse

Designed up this new fan duct for my Ender 3 pro, because i wanted to have a better air flow and also because i wanted to add a led. this works without modifying the head of the machine, just replace the old fan duct with that one. Printing: -20% infill -PLA -0,2 mm nozzle Then you can add a led and running it on 5 volts with a resistance (330 Ohm; depends of the led you're using). In this case be careful that the led is not lower than the nozzle.
