I took this (https://www.thingiverse.com/thing:2675541) and added four of these (https://cults3d.com/en/3d-model/home/parametric-led-tea-light-candle-hat) to make a model with flames.

This was printed for a piece of mixed media art being produced by my partner, so I then scaled the model in Cura to from 150mm to 35mm tall and printed it as per the print settings.

I used no support for the drips and they came out remarkably well but I suspect if you want to print it full size you'll need maybe tree supports for the drips.

Cover photo shows two sets in a pool of dripped wax created with hot glue and then painted. Purple photos are exactly as printed with no cleanup (still on the bed).

I've left the STL full size though to make it easier to use for other projects (it's easier to shrink than grow when scaling).
