airfoil file for 3d printing

Hello, I’m looking for assistance with creating an airfoil file for 3D printing. In particular, I need two 3D airfoil files in STL format, one of NACA 0012 and another of NACA 2412, both with a chord length of 15 cm. The 3D printing process is very detail-oriented, the airfoil file must also be precise in order to yield the best possible results. I am looking for someone with expertise in this area who can create an accurate file. Please let me know if you think you can supply me with the ideal airfoil file. If so, could you also provide me the planform/reference area of the corresponding airfoils?
