3D printable aquarium cave, single solid object. Front side open and flat for glass viewing, all other sides closed rock. Size 45x20x22 cm. 6 thick Horde columns at front only. Left and right sides are solid rock walls. Two staircases on left and right sides, starting at bottom and going inward (away from front, not facing viewer).
