Loved History of the World Part 1 as a kid and once I got a 3d printer wanted to make a model of it. After searching the internet all I could find was a low detail sketchfab model, since it was the right shape I opted to just and a bunch of stuff to it to make it look better and this is what I came up with
Original model made by mitchaiet on Sketchfab
