My WWII Atlantic Wall style 40k bunker that I made from the two pieces of styrofoam packaging material that came with my replacement sink garbage disposal. The grating for the roof is from a metal vent port on the side of my old desktop computer case. The large artillery tube sticking out of the first floor is made from a free pen from one of the big Philly cheesesteak places (I think it was Gino's).
I built the bunker so it would fit into the rules for the 40k Bastion terrain piece with heavy bolters on all four sides and a roof for models. It took some time to build and paint but overall was pretty cheap and I'm really happy with how it turned out. The base is decorated with the broken helmet of an Eldar guardian painted in the style of one of the guys in my gaming group. #warhammer40k #40k #terrain #warhammer
