A (mostly) scale model of the Spirit and Opportunity Mars rovers (https://www.nasa.gov/mission_pages/mer/index.html)
I designed it in Onshape as two separate pieces, the chassis and the solar array, and glued them together after printing. I uploaded both of these STL files, as well as an STL of the completed assembly.
The wheels all spin and the wheel mounts also rotate allowing it to drive like an actual Mars rover. I tested it on some pebbles and it could easily drive over the uneven surface. The scope and camera attached to the solar array also rotate.
Some of the details didn't print as well as I hoped so I enlarged them in the STL files that I uploaded. Also, I plan to make a new version of the solar array with more moving pieces, like folding solar panels.
