Mine and processing plant
The real reason for the my scifi settlement is the location of a nearby mine. The mine was designed slightly differently as I wanted to keep the footprint small but still have an impressive looking model. I had some cardboard tube and I like the idea of a massive entrance leading down into the into the bowels of the planet. I cut the tube on an angle and built up the rocky cliff with polystrene and glued a piece of MDF onto the back with the intention that the mine would be used against the side of a table (or a larger feature).
Some extra details were added to the entrance with a ramp made from textured plasticard, cross-stitch glued inside the tunnel and some angled plasticard strip on the edge of the tunnel. The rocky wall was textured and a vent
was added to the top of the mine.
