I purchased and downloaded the Fat Dragon Games – Copper Dragon: Caverns 1 PDF. They are cavern tiles, and they look awesome printed out. Printed a bunch out then mounted them to black foamboard. I cut them out and made a bunch of cavern tiles. I like the way they look, and that I can just lay one out as my players are exploring, dropping a new tile as they move further in. This map is a representation of the tiles laid out. It is also one of several caves in the Deepfall area of my campaign. It’s a random cave I can drop into the map depending on where the players go. I like most of this map, though I am not happy with the steps down to the next level. They just don’t work for me, need to make some adjustments for the next one.

Here is the tile layout of the map, using the Fat Dragon Cavern Tiles:
