Originally published here: 216 Kleopatra scaled one in four million by tato_713 - Thingiverse

I did not render this model, I just resize, soften and simplified it Windows 3D Builder to share the same scale as other objects. The original file is the revised model from Shepard (2017).
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. 

216 Kleopatra

Kleopatra is a relatively big asteroid with a noticeable bone shape. It is though to be the result of a triple system that colide at low speeds. It has two known moons or moonlets: Alexhelios and Cleoselene. The system does not form part of any asteroid family, so it's part of the background population.
