International Space Station | All Stock Parts
This is a International Space Station (ISS) replica that is made fully with stock parts. You can watch the building of it on my YouTube Channel, or here. It has a total of 241 parts, which may lag your game with a slow computer, but it is very detailed. There are also plenty of docking ports to dock other craft to. All the pieces are connected by docking ports, so you can launch each module separately using sub-assembly.
