My advice? See if your local library has a maker lab. If they do, they might have a 3D printer you can use to make your figures and classes on how to use it in the first place.
Ah, thank you but I wasn't looking to make figurines, which I now realise is what NSminiature was talking about! I draw standees and I liked the idea of printing them onto acrylic tokens instead of cardboard.
Check out vograce.com, you can get custom acrylic standees there for super cheap, with a min order quantity of I think 3 per design, which you'd probably be doing anyways for this. I've used them myself and can highly recommend.
