NASA offers many 3d printable files on their website. The even offer an International Space Station .stl file but it does not have great detail. I went to their International Space Station model https://nasa3d.arc.nasa.gov/detail/iss and got the .fbx file. I converted that .fbx file into a .stl using Fusion 360.
This file is currently no where near ready to be printed but I would love some help trying to get there.
Thank you
