I am looking for a really realistic rocket engine(see attached file). I want the engine to be from the space shuttle if at all possible. I want it to be extremely detailed (more so than the file below) and be able to be 3D printed. Below is the best rocket engine that I could find but just does not cut it with the amount of detail I am looking for.
‘rocket engine’ is a misnomer… true rockets really are combustion chambers and exhaust funnels. Can you share a picture of the shuttle with the area you want circled?
