Jay,

Thanks for posting these files; I think these are great!

Since I 3D print nosecones directly from RockSim using the Export 3D model function; I prefer to print these 2 part constructs using a smoother more tangential fit between the nosecone tip section and the transition following it, see attached files. For blunted ogive nose cones like these; I use a Power series shape (Shape control 0.3 to 0.6) for the tip part and a Sears Haack (Von Karmen) shape (Shape Control 0.45 to 0.75) for the transition.
