Four-Entrance Aquarium Moss Dome

A dome-shaped aquarium shelter with four arched entrances and a perforated surface for moss attachment. The open bottom allows direct placement on the substrate, while the entrances provide natural hiding spots for fish and shrimp. The perforated design supports water circulation and oxygen exchange. Due to the dome’s geometry, support structures are required during 3D printing to achieve clean arches and stable overhangs.
