Dual part cooling fan mod for Elegoo Neptune 2.

Deleted the ugly and noise inducing grid in front of hot end fan.

This is actually remix of @terrorhai remix (https://www.printables.com/model/392704-v21-printhead-for-elegoo-neptune-22s), but decided to put it here for easier finding. This mod improved overhang performance clearly, compared to one fan Satsana setup.
