My brother does 3D printing. Usually, it's models downloaded from the internet, but sometimes he quickly models various household items. So, I think he's well aware of all these features related to ribs, layers, stands, and so on. If that's what you're interested in, I can give him a link to the post.
And yes, it's a cool idea. Ideally, you could then paint the model with brushes, and it would be even better.
Hmm, I meant, has anyone done this with Heroes 5? =)
And yes, I also have some experience with 3D printing. I modeled and printed 8 buildings from Heroes 3.
