Warning: Since I've been getting a lot of requests, I've put it up for public sale here on MMF; but, if you're not in a hurry, I recommend waiting, because I plan to add it again to some Kickstarter project later this year, and it will be cheaper there.
A set of pieces so that, once printed, you can build modern 20th century style buildings, the typical red brick urban ones, with which to set your role-playing games, board games, wargames, dioramas... mainly intended for Zombicide, Walking Dead or MCP style skirmish games, created for tabletop wargames at 32-35mm scale (of course you can rescale them, although if you make it smaller, some small parts may cause problems or disappear altogether)
