All the small NASA solar system probes are linked to this discovery page. It's sort of the new version of the grand tour. Every mission has an education section with paper models of the probes you can print and fold together. You have good photos plus the basic shape with textures of the satellites. It would take very little to do these in a 3d program and add the bulges, tanks, and jets where they go. The site might even be willing to host your model when you are done.
