This steampunk-style submarine makes for a great addition to any fish tank or shelf display. It features plenty of small details like rows of rivets along the hull, three portholes on each side, and a classic periscope on top. There is even an open hatch at the front and a propeller at the back to complete the look. It has a rugged, industrial feel that looks like it could have come straight out of a Jules Verne novel. Whether you are looking to add some character to your aquarium or just want a cool nautical piece for your desk, this model fits right in.

--- 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).
