30mL dropper bottle stand / "foot"

A simple model that a ~22mm diameter dropper bottle presses into, for increased stability.

No special print properties - base is only 3mm thick under the bottom of the bottle, so this adds stability by being wider, not by adding weight.  Picture prints are with “fuzzy skin” painted on the outside surface for grip (available starting in PrusaSlicer 2.9.0-alpha?), but all fuzzy skin or none should both be fine.
