XJ99C Fan Mod for @Leander's Fan Showcase

Really like Leander's model, tweaked one of my fans to work in it. Showed a peak of 4m/s (1000ft/min) flow with it clamped down, and some silly amount of cranking. 

Decided to bypass the rachet mechanism, so it's mounted direct to the second stage output.

Will need a bit of suppport on the blade tips, 0.2mm layers.
