Ball bot Kickstarter STLs by Printed Encounter
And all for the princely sum of... about £8.
Lots of fun, lots of character - I can easily see these being used in all kinds of settings, and the sculptors looking at other parts they can do as well.

Nicely detailed - the painted examples are pretty snazzy too.
