[Wikipedia] Kokeshi, are Japanese dolls, originally from northern Japan. They are handmade from wood, have a simple trunk and an enlarged head with a few thin, painted lines to define the face.
And now they can be printed too.
Dimensions can be tuned in OpenSCAD using kokeshi.scad provided file.
This model is printed in three parts. I used some support for the hair.
You might want to use different colors for the different parts.
Once printed, feel free to paint it or to decorate it with stickers.
