Update:
In case more airflow is desired than the original heavy slimming, I added a V2 that adds 30% more cross sectional airspace by slightly widening, raising, and thinning the walls. It should likely print the same. Same print time.
I really like Admant77's fan duct, but wanted to slim it down a bit as the bubble shape was a tad too much for me. Many thanks to him for the hole positions and design concept, without having to go into the Creality references.
This is a very similar design, but slimmed down a bit for faster printing. It uses 60% the material in 60% the time as the finned version.
Print in normal use, flat position.
