This is my attempt to design a well-performing spinning top with high angular momentum and little air resistance. If you get the hang of it you can get it spinning for more than 2 minutes every time.

I printed this on a resin printer. I'm not sure if it can be printed with an FDM printer! But if you do attempt it, I think you should try to use a high infill percentage for the outer ring. That way, your spinning top will have higher angular momentum and will spin longer.
