Plasma Vortex Blade Fan Noctua Fan Mod for Noctua A12x25

UPDATE v8:
Did some fitment optimization and also compared against stock. It is a slightly noisier, however definetely puts out more air flow. That's a win in my book :D guess the noise comes from the vacuum nozzles of the rim Suggested printing orientation is upright with support for the inner ring overhang. Otherwise the wing profile is too steep and would get messed up by support.

Edit: just did a test on 5V, the result was a really quiet operation and also it feels like twice as much throughput than the original fan. It really makes a difference.

The blade sweep extrusion spline is inspired by a high voltage plasma vortex spinning in between two tubular magnets.

Suggested print settings:

no rotation - designed to be printed on bottom,
support for 80°/10° overhang, depending on your slicer,
6 perimeters,
detect small walls on,

Support:
- z distance 0.15mm / xy distance 1mm / z over xy
- type zig zag, 1.5mm line distance
- interface layers
- support only horizontal, buildplate only

:)

The adapter is for use on a desk USB fan with 2mm axle.
