A charming, Q‑style rendition of a submarine—perfect as a decorative ornament or a fun little toy to play with in your hand. The propeller spins smoothly, and the model even floats effortlessly on water.

I’ve divided the model into two separate print files, allowing you to easily assemble it in different color schemes. Printing both discs takes just over an hour to complete.

If you prefer a single-color finish, simply join the parts from the two discs together—the printing process will be significantly faster.

An opening has been预留 at the top of the submarine; feel free to experiment by adding a few small nuts inside as ballast and see if you can achieve deeper dives.
