Rocket

I put the body of the rocket separately because it would take more than a day to print the nozzle, nose cone, and body. This rocket is designed to fit with a pvc type rocket motor, and the nozzle goes with it as well. some of you may like making your own rocket motors, like me,  and pvc pipes are perfect. This rocket goes with 3/4 inch.  The rocket body is 350 mm long. For the pvc pipe, it should be 3 1/4 inch and sand it down another 1/16 inch. The total height including all the parts assembled is about 1 ft 7 inch. The nozzle diameter is a little bit smaller than the diameter the pvc pipe because the heat from the exhaust melts the walls of the throat so I made it smaller for faster flow, and it will maintain it's velocity until the rocket motor goes out. I recommend that you print the nozzle at 100% in fill because if it is not, then when the heat melts threw the wall, the exhaust will flow everywhere.  For the nose cone, there is a tube where you can put a eyes lag thread for the parachute.
