Windmill Blades (Based on NACA 4 Digit Airfoils)
thingiverse
These are a couple models of blades I designed specifically for windmills. Based on the NACA 4-digit airfoil database and libraries penned by Parkinbot, his propeller library, repeller library, naca 4 digit library, and shortcuts library are necessary to compile these models. To print the blades, download ModelNEW.stl. Each blade measures about ten inches long and five inches wide. If you want to edit the model, I suggest using BladeNEW.scad. This is the source file for ModelNEW.stl. Both files marked "old" are an experiment where I designed the blade frame from scratch rather than subtracting areas from the finished wing.
