Ender 3/Pro Ender 5 Cooling Fan Duct

I manually put some internal supports, but it doesn't interfere with the airflow, so you can print completely without support. In the small lock that is on the outside, I also put a support manually, just remove it with a blade. Attention: I recommend you print this in ABS, due to the heat near the nozzle, ABS has greater heat resistance.
