OpenForge Daern's instant fortress

This is an encounter of some sorts. This is the 3D model of the D&D 5e magic item ''Daern's instant fortress''.
The describtion of the item goes as follows: The fortress is a square tower, 20 feet on a side and 30 feet high, with arrow slits on all sides and a battlement atop it. Its interior is divided into two floors, with a ladder running along one wall to connect them. The ladder ends at a trapdoor leading to the roof. When activated, the tower has a small door on the side facing you.
The tower is made of adamantine, so this might help you for your painting scheme.
Mine will be unique in the sense that the second floor has a teleportation circle, If you don't want this, you can just print the first floor or roof 2 times.

I'm very curious what you guys do with it and would really like to see some mades.
If there are any suggestions, feel free to leave them.
