This set that can be used to showcase the extreme difference in scale between our star and the largest of the gas giants and our homeworld. This set has been scaled such that Jupiter is about 10mm across. Even so made to scale the Sun towers above the two objects as an 109mm globe.
If one wanted to add Earth to scale as well, Earth would be 1mm. This is not printable using 3d printing, however such a set can be found at

A spare stand alone micro Jupiter is also available
here.
