Air Compressor Rockets

This project was inspired by a fun activity we saw someone doing at a park with construction paper, air compressor, and a fun grandpa with is kids. I am not a grandpa, but I do have kids. The idea is, You build a PVC chamber of some sort, and place a valve on the end. In my case I placed a sprinkler valve. I then wired the sprinkler valve to an arcade button and powered it with some 9 volt batteries, later upgraded to a Dewalt battery adapter.Then you pressurize the chamber, press the button, and launch. The paper rockets could not handle that much pressure, so I thought, “Hey I like 3d printing, and I like attempting to design stuff” so here we are. This project contains most of my iterations thus far, please feel free to expand and upgrade the project as you wish. All the CAD files are attached. NOTE: one thing that was fun about the paper rockets was that the kids got to pick colors, cut out their own fins, make their nose cones, and design them. So I tried to keep that idea in mind
