This is a midlife update for my entry for the Fan Showdown. Maybe +1-2% flow over the original T33 MkIII

Description

PDF

This fan fits the Noctua A12x25 metal hub.

The Redux has an updated hub and wingtip, but retains the original blade profile. 

This fan, https://www.printables.com/model/299994-xj99c-noctua-nf-a12x25-mod is probably a better design, building off the things I have learned alon the way.

Print 0.1-0.2mm, use support, do some sanding, if you like. 

Step file included so you can fit it to whatever hub you want.

Quick testing showed 1-2% improved flow from hub & tip optimization.
