The little guy loves blowing out candles, so I got a large candle, but it's obviously a bit unstable, so I made a candle holder out of PLA. Here you can see the two parts. I started with a stock half sphere, and took away a cylinder from the center. I added a bit of a bevel to the cylinder with a slider.
(Is this fireproof? Not at all. You better believe it needs to never be allowed to burn that low)

You could make a lost wax casting in bronze or aluminum.
One thing I learned from experience, if you use plaster (gypsum) for the piece, you need to dry it out all the way to anhydrite.
Plain casting plaster will have a couple H2O molecules for every CaSO4, and it will flash into steam when the molten aluminum hits it..

I picked up a kiln a few years ago for just that sort of thing. I think it's a really cool idea.
