As a promotional System76's Kate Hasen created a set of adorable bots. For practice I created little figurines that tried to capture what I thought was their individual charm.  The bots come complete with stand and when last printed came out fine. However, you may want to print them larger to get the finer details and to strengthen some of the parts.
