Thank you for posting these images KONNOC. I do not have any models, physical or stl, but I too am interested in building a Crait layout for my West End Games Star Wars minis. Per the Last Jedi visual guide, Crait was an old base used by the rebellion, so it will work quite well for anyone doing a campain in the Imperial era or in the time of the First Order.
Good luck, I will be watching this space.
