Windmill Blades (Based on NACA 4 Digit Airfoils)

These are a couple models of blades I designed for a windmill.
These are based off of the NACA 4 digit airfoil database and the libraries written by Parkinbot. His propeller and repeller library, naca 4 digit library and shortcuts library are required to compile the models.

If you want to print the blades download ModelNEW.stl. The blades are a little less than 10 inches long and 5 inches wide.

If you want to edit the model I recommend using BladeNEW.scad. This is the source for ModelNEW
