Windmill Blades (Based on NACA 4 Digit Airfoils)
thingiverse
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.stl. Both files marked will old are an experiment I did designing the blade frame from scratch instead of subtracting areas from the finished wing.
