Star polygons or polygrams, from 5-pointed all the way to 13-pointed. And all its varations.
Notation of the stl files is in Schläfli notation (https://en.wikipedia.org/wiki/Schl%C3%A4fli_symbol) where {p/q} means p points in the star, and q means how many points you travel along the star points with each line. q = 1 means regular convex polygon as the value of 1 means you just traverse to all neighbors in order. They are not stars so I did not include them here :)
What is included is 2+. 2 means you skip one and travel to the next so you get a star-shape, as with 3 or 4:

Most known star shape is probably {5/2} or {6/2}, both available, but also {13,6} which is very pointy
Use them, share them, add them to your prusa slicer gallery! It's all public domain.
