Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4685458.

A star that can be hung or just place on a table. There is a small hole near the top of the star for a thread the size of a fishing filament. The hole is slightly larger on the backside than the front.

You can use scaling in the Prusa Slicer to make the star any size you want. The size in the .stl file is about right for use on a Christmas tree.
