For the already pretty good Seabreeze Turboaire II. I'm showing ~10% better flow, for only a couple dB louder.

Just to see if there was any more performance to be had.
From the stock blades;
+1° AoA at the tips,
+4° AoA at the root,
+25mm chord at the tips,
added dihedral curve,
and some winglets.
Blades printed standing vertically, will need some supports, 0.2mm layers, recpommend 4 perimeters, PETG or other semi structural filament.
Built on ideas from another of my fans, https://www.printables.com/model/299994-xj99c-noctua-nf-a12x25-mod
Original and mod in pic with a 120mm fan for scale.
