Add a playful pirate touch to your setup with this Treasure Map Aquarium Cave, 3D printed in matte plastic and designed like a rounded underwater hideout with an arched opening, map trail details, a compass motif, and little coral-like accents around the base. The shape gives it a fun treasure-island feel while also creating a cozy decorative cave look inside the tank. Its soft gray color makes it easy to match with different aquarium themes, from simple layouts to more adventurous ocean-inspired scenes. A great choice for anyone who loves creative fish tank decor, pirate details, and unique 3D printed aquarium pieces with character.

I test all my models with default Bambu Lab slicer settings: 0.2mm layer height, 10% infill, tree supports. No complex tweaks needed. If a model requires special settings, I include a prepared 3MF file (rare).
