This model rocket stands at 35 inches tall! (iPhone 5s for scale) It consists of 5 main pieces and can use 2 sizes of engines. It is capable of using 29mm engines(E16 or F size) or 24mm (E9 or D size) with the engine adapter. This rocket is a fully functional model rocket that can be printed on any printer with a build height of 7 inches or more. Be safe and have fun, Thanks!
P.s: I will have a video and pictures of the first launch soon.
Use 20% for the base, 100% for the body pieces, and hollow for the nose cone.
I recommend using .3mm layer height because this took me 12 hours to print using that. The additional launch lugs can be used if you are using a thicker .25" launch rod. The adapter can be placed into the rocket, and then the engine into the adapter if you are using 24mm engines. Also, you need two length sections and one top length section to make the rocket shown. You can use only one length section if you want a shorter, lighter rocket. My final launch weight for the 35in. rocket was ~10.5 oz. I used PLA. Good Luck Building!
You will need masking tape and super glue for the main assembly. wrap the connection points with tape until you get a snug fit for each section to the other, then you can permanently glue them with super glue. Also, use tape on the nose cone to make sure it fits on top tight, but not too tight as to not get ejected. The lugs can be glued on with super glue as well. For the adapter you should use the tape method as well. Finally, use tape to get the engine to fit snugly inside the adapter or base section.
Can be purchased or made with a trash bag. Use a toothpick to push the string into the hole on the bottom of the nose cone. Then, add glue and break off the remaining toothpick. Tape or glue can be used to attach the other end to the rocket.
