There are cities inside the massive head of a rotted out celestial being (name it!) but cities inside the partial shell of a small planet? …I dunno, I can’t think of one of those. Maybe that’s why our model of the week is so cool.

Jukka Seppänen recalls a concept drawing of a city inside a moon that has been destroyed. When he saw the drawing, he immediately wanted to create it in 3D. WHO WOULDN’T!? Jukka uses Blender, Sculptris, SolidWorks, and 3D-Coat for modeling and has a knack for modeling intricate structures. The Moon City model he created is just incredible, with loads of buildings and loads of details, along with a few massive craters on the outside (because meteorites don’t hit the inside of a hollowed out moon floating in space).

He printed this on his FlashForge Creator Pro 3D Printer. At the default size, running at 60mm/s with a 0.2mm layer height, he says the print took around 12 hours. Yes, you can have your own moon city 12 hours from now. Scale it up life-size and it’ll only take a few hours/decades more to create!

You can download the model and see the step-by-step on Thingiverse.
