[Bathtub Toy] Cute Mini Submarine with Freely Controllable Diving in Water, 1-Hour Print

A cute mini submarine that allows for freely controllable diving in water, printing in just 1 hour.

It uses varying print densities to ensure the submarine's center of gravity allows it to float steadily in the water.

Featuring a uniquely designed hollow structure, you can control the submarine's diving depth simply by filling it with varying amounts of water.
