8. 3D print the files and gather parts

9. Start assembling the rocket

  • Thread a flame-resistant string or shock cord through the tube inside the fuselage

10. Tie the string off on the bottom end with two knots to keep it from coming out

11. Tie the other end around the bar in the nosecone

  • You can use tweezers or a paperclip to get at the string when it's inside the nosecone.

12. Push the fuselage into the lower body. It should be a very tight fit to keep it from coming loose in flight.

  • Depending on your printer, you might have to sand a little bit off or put a piece of tape on the side to get the perfect fit.

13. Tie a streamer or parachute to the string

14. Roll the streamer and push it into the fuselage

15. Slip the nosecone on. It should be a loose fit so that the ejection charge will pop it off.

  • Depending on your printer, you might have to sand a little bit off or put a piece of tape on the side to get the perfect fit.
