This model is made by myself using MATLAB R2016a on the height map of the USGS site from the Dawn mission. On this scale the Moon is a basketball and Mars' moons Phobos and Deimos are 2 and 1 mm respectively. It's also included a one in four million scaled model for more details. In this scale the model is 14cm in diameter.

The file's names explained:name_1_x_10_y.stl is 1 : x * 10 ^ y. So _1_6_10_7 is 1:600000000 or one in 60 million.

4 Vesta

Vesta is the second largest object in the main asteroid belt, the largest asteroid considering Ceres as a dwarf planet but not an asteroid. It is one of the biggest object not hidrostaticaly relaxed, so it's automatically excluded from being a dwarf planet. Its irregular shape is carved by many features like the south pole Rheasilvia crater, and the multiple large equatorial fosae. Vesta is though to be a protoplanet, a remnant of a failed planet. It has a differentiated nucleus, which means that is was a planet primordial block, but its acreation was interrupted before the formation of a larger body.
