I'm wondering if anyone makes scale models of "bumpy" worlds, such as smaller moons or asteroids. Or if there are 3d models, which could be used for custom 3d printed models.
Among the "bumpy" worlds which we should have sufficient data for are Saturn's moons Iapetus, Hyperion, and Phoebe, as well as the asteroids Vesta, 433 Eros, and 25143 Itokawa.
I'm not sure whether we have enough views of Mars's moons Phobos and Deimos.
I think Iapetus would be a particularly dramatic scale model. It's round enough to obviously still be a "world", but it has both exotic coloration (two-tone) and exotic form (equatorial ridge, truly bumpy texture).
Larger worlds are smooth as a cueball; most smaller worlds look like a random rock.
