Underground Vault and/or Bunker

thingiverse

Terrain for a desolate wasteland, a grim post-apocalyptic future, or a sprawling colonial underhive world. Scaled for a 15cm wide building platform, this design can be easily expanded to accommodate larger prints by cutting it in half and setting it up vertically. Perfect for showcasing 28-32mm scale miniatures, simply add a layer of flock or sand to the top of the hill and you're ready to go!
