Round Room Adapter
These are some modifications I made that go with the Tower of Terror set to allow round rooms in a dungeon that I thought people may like. They allow for a 20' wide corridor to join to a round room. The tower of terror main set will be needed to use these.
There are three STLs - They are all on a 4x4 tile¸ A left hand wall¸ a right hand wall and a double corridor wall.
I printed at 0.18 Layer Height With 10% Infil¸ should be good with the FDG Terrain profile for Cura.
