Stand for coffee makers such as Bialetti or similar.
This particular one has been designed to fit the basket of a WMF (german brand) electric coffee maker, but other brands might fit on top of it just as well.

The center has a small drip hole to get rid of any droplets or coffee grinds that might get trapped in the middle as the center is a bit hard to reach with a wipe.
Or you just give it a good blow :)

Print instructions

I have printed this on a Flashforge Creator Max with 0.18mm layer height with no supports or brim as the base is almost as wide as the whole model.

You might want to give a little bit more infill to make the base and columns a bit sturdier (e.g. 25%).
