Atlas carries a world, Locke renders one, Pioneer drives through one. The Space Program sends a piece of it four hundred feet straight up. A real flying model rocket: you print the nose cone and the fins, build it on a cardboard tube, and light a real motor under it.
The whole flight lasts under a minute, and every second of it is real physics. The builder's Launch scene flies the same numbers before you ever strike a match.
The rocket follows the Estes Orbis pattern: a cardboard BT-20 body tube carries printed fins and a printed nose cone, so every rocket can look different and fly the same.
Three nose cones, three fin styles, and a colour for every part. The builder shows the whole rocket in 3D, with the same blueprint mode as the Pioneer garage.
Open the builder →Name your rocket and the zip lands with every printable part, colour-coded filenames, and the full assembly instructions. The tube stays cardboard; you print everything else.
Name one →Glue, a BT-20 tube, a 9 inch chute, and an A8-3. First flight goes about 400 feet, pops its cone at the top, and parachutes back to your feet.
Launch day →Model rocketry has been a safe family hobby for seventy years because everyone follows the same short list of rules. Read it once, follow it always.
