This is a scaled model of the solar system. I used earth as the base at 10mm. All the other planets are scaled up/down relative to that. There's an attachment included that you can glue to the back of the sun to stand it on it's side. It has holes to fit 2mm steel wire.
I printed the larger planets in halves and glued them together, then just covered all of them in plaster and painted them.
I made my base 50cm wide. If you want to make the distances true scale the base has to be 30 meters wide :D
The author marked this model as their own original creation.
