Everyone has a model of this figure. Here's mine.
Small is 1" diameter: it could be a pendant, but beware the pointy aggro! This comes in plastic or cast metals: brass, bronze, silver.
Medium is 2", this is a nice print in plastic or steel, but pricey in cast metals.
Large is 4" and I've set this to plastic only; it's certainly printable in steel but you'll need about $500 to do it.
