It might be super tiny when you open it in your slicer. I think i scaled it up like 300% or something to get it to be about the size of my fist. You can (just barely) fit a tea-light inside. When the candle is lit, the flame ball will glow nicely.

I printed with support and the support structure ended up being a nice base for the flame ball.

The flame ball will sit up right without the base but topples easily.
