Accurate model of Mount Vesuvius volcano in Italy, just a lot smaller. Also minus the first 300m of elevation so it looks taller. Some of the overhangs get a little messy, but thats OK - its a volcano.

Runs on baking soda and vinegar.

Print raftless so it fits on the build pad. Also make sure your inset settings work so that the bicarb holder doesn't get welded on during the print. Remove the bicarb holder by pushing a chopstick down the lava tube.
