That's what I did. The center "prongs" are 0.5 ml and the base is 1.1 mL. Upside down could work but what I'm aiming for is the lid holding the holder securely in the cup during transit.(See below)
@Tidal Gardens does that too I think.
If you make print in PETG and make it thinner it could flex a little. That may make it fit snuggly. Or upside down wedged in the cup.
