3D Printed Multi-Cavity Habitat Shelter

A versatile 3D-printed shelter with multiple interconnected cavities for small aquatic and terrestrial animals.

The organic, rock-like structure creates a variety of openings and sheltered spaces where animals can explore, retreat and rest. Its open construction provides multiple entry points while allowing water or air to move freely through the structure.

Suitable for use in aquariums, shrimp tanks, crab habitats, isopod enclosures and other appropriate small-animal setups.

Three Designs

Choose the cavity density according to the animals and habitat:

12 Holes — larger, more spacious openings
21 Holes — balanced mix of medium and smaller openings
29 Holes — denser arrangement with more small hiding spaces

The different cavity sizes make it easy to select a shelter for shrimp, small crabs, isopods or suitably sized small fish.

PETG Construction

Made from PETG (Polyethylene Terephthalate Glycol) using 3D printing.

PETG is a durable, moisture-resistant thermoplastic suitable for use in wet and humid environments. The lightweight structure is easy to position and can be incorporated among rocks, wood, plants, moss or other habitat materials.

Fine layer lines and minor surface variations are a normal characteristic of 3D-printed products.
