I've updated the .stl files with the latest version. This is the version that is being constructed. It is also the one that pictured above.

I've also been asked how someone could learn to make something like this, or just learn about turbomachinery in general. This link, is a link to the textbook that was basically my bible. With this and all of the freely available sources on the inter-webs, anyone could learn this.

Cheers!
