A proud medieval fortress crowning a rugged rock crag, inspired by Trenčín Castle in Slovakia. A tall keep with a timber war gallery, seven towers, crenellated walls and a steep stone stairway climbing to the gate, all on a 75 mm octagonal base. It prints in one piece on an FDM printer with no supports.
