For another fun scale-comparing trick, if you had a model of the whole visible universe, somehow flattened into 2D, with the distance between Sol and Alpha Centauri being around a millimeter, you should be able to fit the whole thing on a half of the Earth's surface.

With the Sweden Solar System scale, Alpha Centauri would be around five times the distance to the Moon out, so there's still a bit of a hurdle visualizing how the two scales fit together.
