This is a functional model of the inner planets I put together for my own graduation cap decoration. The model features the sun, Mercury, Venus, Earth and its moon, and Mars. Orbital speeds of each planet are proportional to each-other, and accurate up to 3 decimal places.
NOTE: Scale 2540% if your parts come in microscopic.
In addition to the plastic components here, I also used:
a #6 sheet metal screw

Planets themselves are included in the files and should be able to be printed, but I ended making mine out of modeling clay to get nice blended colors.
