The Nike Hercules ground-to-air missile was deployed in many parts of the world throughout the cold war, and was phased out when the Patriot missile came along. It was capable of carrying a nuclear warhead.
This model is made mostly of filled solid components to make it easier to scale up or down. You get to choose the wall thickness by selecting zero infill and choosing the number of perimeters. At the default scale, the complete model is 19.5 inches or 49cm tall. At that size, printing with one perimeter results in a very lightweight model. Two perimeters makes a more sturdy model.
The one shown is printed in E-Sun Solid White PETG and painted with Krylon Italian Olive paint+primer, which makes a good army olive-drab.
This model lacks some features needed to use it as a flying model rocket, but it could probably be modified to be such.
The Hercules upper stage has designed-in supports for the upper fins. You will need to score them with a knife on both sides to remove them after printing.
