Based on the ancient sculptures from the Hamangia Culture, around 5000 BC. https://en.wikipedia.org/wiki/Hamangia_culture
I made two versions of each figure. I found they printed best flat on their backs, but if you want round backs, you can print them in the default orientation. When they're on their backs, the arms and face have better surface quality, because I'm printing with a single extruder. Turn support material on. I set mine for about 28° overhang threshold. I used about 0.2mm layer height, and used textured spraypaint to fill in surface and smooth it out, but you can switch to a more fine resolution if you want.
