Turbine Scad

I'm working on some mini wind power devices, and ended up making this modifiable turbofan making code for OpenSCAD. As it sits it takes a 1/4 20 bolt through the hole, and will fit on my Monoprice Maker Select V2 printer. As you can see by looking at it, all you need to do to make it fit other projects is to change the user definable parameters until it meets your specs.
