3D Printed Terrain
For terrain I highly recommend Greeblecity. Below is one collection and a few city ruins. We primarily play with 1/400 scale or ~2-3″ models. These sculpts are wonderfully put together and can create a nice looking city terrain for your games. For 1/400 scale we printed the below terrain at 200% scale so the buildings are a consistent scale with the Mechs. Conveniently a 200% scale also fits on a Monoprice Mini printer.
You can find more free designs from the sculptor below:
