We made these at our school to give out as trophies for students that accomplished our programming course using Dash & Dot. It takes about 5 hours on a 0.2 layer height setting, they're not perfect but we don't mind, certainly our elementary students don't seem to mind either, kids are happy with their trophies!

The model is perfectly symmetrical and the bottom is flat, the support is for the middle part, easy to remove. The imperfections lie within the depth of the holes on the sides, only visible to the very critical eye that could spot a crossed eye ant or something like that.

We printed with PLA but you could try any other material.
