A tiny "add on" kit, that scales the gas giants according to a 200mm "Sun". This allows one make DIY scale representations if only he finds a something like to a styrofoam ball at the right size.
An alternative version of this kit is available
here, that includes Saturn as a bifurcated globe for the possible future easy addition of rings.
Set includes:
Jupiter: 20.0 mm
Saturn: 16.74 mm
Uranus: 7.28 mm
Neptune:7.07 mm
The terrestial planets are unfortunatly unprintable in this scale, however if you are interested in putting them together some other way the sizes of them would be:
Mercury: 0.70 mm
Venus: 1.73 mm
Earth: 1.83 mm
Mars: 0.97 mm
Pluto: 0.34 mm
