A stencil / mask to airbrush / spray paint the Space X logo on to the Falcon 9 / Heavy rockets by JRad (Great model BTW!). Curved to match 21mm radius of the fit stage. Only 1mm thick so it should fit othe as well. I suggest printing with outside curve facing down support material since you don't care about surface finish anyway. Use VERY LIGHT spray each layer as it may leak / drip since it is not a 100% flush mask.
