Rocket

I designed this rocket to be assembled separately from its body due to the lengthy process of printing the nozzle, nose cone, and body individually. This design allows it to seamlessly integrate with a PVC type rocket motor, including the nozzle. Some individuals may prefer crafting their own rocket motors, similar to my preference, and PVC pipes are an ideal choice for this endeavor. The rocket's body measures 350 mm in length, while the required PVC pipe should be 3 1/4 inches in diameter. To ensure a precise fit, the pipe must be sanded down by 1/16 inch. Once assembled, the total height of the rocket stands at approximately 1 ft 7 inch. Notably, the nozzle's diameter is slightly smaller than that of the PVC pipe due to the heat from the exhaust melting the walls of the throat, which necessitates a faster flow rate and maintains velocity until the rocket motor deactivates. I strongly advise printing the nozzle at 100% infill density to prevent the exhaust from escaping through any gaps when the heat melts the wall. Additionally, the nose cone features a tube designed for securely attaching an eyelet thread for the parachute deployment system.
