For this project I had to create a model rocket that would be 3D printed. I first designed a rocket using a program called Open Rocket. I then modeled the rocket using Solidworks and 3D printed it. Lastly I cut the fins out of chipboard and glued them to the rocket, and I shaved down the connectors to the pieces could fit together well. Overall I learned how to create a rocket using Open Rocket, and how to setup the 3D printer to be able to print a model from Solidworks.

With the Open Rocket program I was able to simulate how high the model rocket will be able to fly. I used this to test how high the rocket will fly with the different engines that were available to me; the C6, B4, and A8. With the C6 engine the rocket was projected to fly over 2,500ft high. Also in the simulation when I lowered the humidity the rocket flew higher.

This is the fully constructed and spay painted rocket. The rocket was approximately 11.5in tall and had a diameter of 0.9in.
For the rocket launch I used a C6 engine. Sadly I was not able to find the rocket because it went too high and far. I felt that my rocket did very well. It went so high that you couldn't see it anymore. I felt that the simulation in Open Rocket was very close to what actually happened. Also I felt that if I made my fins more accurate to what I modeled I think that the rocket would have flown straight up.
