A cave for decoration, as a hiding place or breeding room in the aquarium. Suitable for example for fish and shrimp.

The entrances in this version are about 30mm wide and 45mm high. There is room for somewhat larger animals.

Model is scalable in several slicers.

The surface is slightly rippled due to the manufacturing process, algae will probably grow here over time, resulting in a more natural look.

Overall dimensions approx: 180x160x65mm

If you scale by 50% you will get a Version for smaller shrimps and fishes with an entry of approx. 15x20mm.

PETG, at max. 0.20mm Layer height for the small version.
Print this with 100% Infill or it may swim and you will have to put sand or stones into it :-)

USE Organic / Tree support for the roof ! You can break them afterwards and shake them out of the cave.
