Lovely stuff! Its strange, color printers have gotten more and more common but paper scenery (and figures) seem to have become a lot less common these days, and I'm not convinced that 3d printing is to blame, they seem like very different tools to me. Also actual understanding of the architectural side of things, not just on castles and military structures but on the every day things, that is something I think we can learn a lot from in wargaming.
