Parametric NACA4 library

thingiverse

This library is a stepping stone for another project I am working on at the moment. I did not change much to the slightly demented (sorry David) code by buzz, but: 1) Removed the MCAD dependency 2) included most on the calculations in the airfoil module to make it portable 3) Added the possibility to change the NACA profile on the fly Instructions 1) Download and copy into the OpenSCAD library folder 2) include into your project using the "use" directive 3) call the module: airfoil(); // creates the airfoil profile 8412 as before airfoil(8,2,15); // NACA-8215 profile Have fun with it!
