Launchable Model Rocket

youmagine

This is a flyable model rocket that arrives in 3 printed components: nose cone, mid-section, and lower-section. Printed on an Ultimaker 2 using PLA filament. Launched with Estes A8-3 rockets. Soars extremely high and flies straight. Attached are 3 STL files (one for each rocket component), and the original design file in SketchUp. Print all components at the highest quality resolution possible. You can print without supports. Print the mid-section and lower-section upside-down. You may need to sand some parts together tightly. For the parachute recovery system, create your own. Use a long rubber band as the shock cord. Cut out a parachute shape (circle or hexagon) from a heavy duty plastic garbage bag. Tie kite strings of equal length to holes punched into the parachute. Snake the rubber band through the radial support structure inside the mid-section, loop it around the structure, and tie it off securely. (You may want to use a little hot glue to make sure it doesn't come undone.) Tie the other end around the radial structure of the nose cone. Finally, tie the parachute cords around the radial structure of the nose cone. After securing the parachute to the rocket, use a little acrylic glue to cement the mid-section to lower-section together tightly. Slide a rocket engine into the bottom of the lower-section leaving a quarter of an inch exposed. Sand the inside a bit if the engine doesn't slide in easily. The fit should be snug, not too tight. It should come out with some effort applied. Follow model rocketry techniques to launch and recover successfully. Have fun flying!
