I found a pot on grabcad, made a base/stand for it, and then took the bubbling liquid from the Lich Lord - Scenario 8 - The Dark Cauldron thing.

I used Prusa Slicer to directly add text to the base to make it into a trophy.

It is lit up with a flickering LED tea light that is just under 37mm in diameter.

A person could easily use this as a Halloween decoration.
