I just spent an hour of my life creating a figure on here. https://www.heroforge.com/

You can design it, and either pay for the 3d file, or have them make it for you. Pretty sweet if you ask me.

Nice stuff guys

I'll add that TinkerCAD is a great free web based CAD thing. You can make basic stuff and it's what I've been using recently to make some hobby additions.

If you are a car guy, this seems an interesting resource for bodies
