This link is really only images of the finished assembled steam engine.Click on "poetryinmotion" to see and download all of the STL files needed to build it. The model is full size so it must be scaled when printed. Unless you have a print bed thats 10 feet long. All the parts have holes where you will need to provide fasteners, you will have to provide additional cleanup etc. to ensure proper fit of the parts

Good Luck.
