Modular Fish Caves

Modular aquarium / terrarium caves with different possible geometries.You can connect each different module in every configuration you want. This way you can have your tank caves with the geometry you want, on the configuration you prefer, with just the right amount of hides you need. You don't need to print with 100% infill for them to stay underwater (I printed the modules at 5% infill). Just heat a nail, holding it with pliers, and press the nail on the marked holes on the side of each module. This way, water can flow inside and the trapped air can flow out, sinking the module. After printing the modules and the cave geometry you wanted, you need to also print the insert connectors to connect each module to each other, in the configuration you want (left / right / below / above), simple and easy to connect an mount. You can also print the insert ends and assemble them on the place of the connenctor holes you will not be using. I suggest to print the modules and caves with fuzzy
