A NASA page provides plans for a paper card model of the four Magnetospheric Multiscale (MMS) spacecraft: MMS EPO Card Model.
The page also includes detailed plans for an Atlas V rocket paper model.
The paper model plans come from Dr. Alfonso X Moreno, who runs the website at AXM Paper Space Scale Models and also the AXM Paper Models Blog.
