Moon city Free 3D print model

Updated version availble here: https://www.cgtrader.com/3d-print-models/art/sculptures/moon-city-multipart-lamp-edition

A city inside a ruined moon. Based on a drawing I've seen around, but couldn't figure out the original artist...found many derivatives only.

Anyway I was looking for inspiration and when I saw the drawing I immediately wanted to try creating it in 3D, and this is the result.

This is a very long print at default scale, which was pretty much necessary for me to print some of the details on the buildings. Took around 12 hours at 60mm/s and 0.2mm layer height. I did make a test print half of the default size, and while it did print I wasn't satisfied on the quality. The buildings and whole of the inside requires no supports, on the outside you might need some at the start.
