This is my best fan design, to date.
Recommend 0.15mm layers or smaller, any filament, should print without support but might need a brim.
The tail might improve flow ~10%, the intake only about ~2%. Graph shows a rough system curve for Season 5, fan showdown.
Did some DIY testing, runs around 1950RPM, 49dB, 3.10mmH2O static pressure, 120cmh.
Some independent testing, https://www.reddit.com/r/FanShowdown/comments/15f1thq/upgrades_to_test_bench/
