Warning! These are SUPER TINY.

I was able to print all four ship hulls in 22 minutes.

There is another file with larger models and a larger variety, but you can also just scale these up as well. Up to you. Detail at this scale is pretty minimal. Sizes range from 1" to 1.5".

I added an object file if you want to edit them on PC.

NOTE- I would recommend lowering them in the slicer to get “flat bottoms” so they are

1. Easier to print without supports
2. Easier to mount on bases or sit on a table top without a base.
3. You can set your own “draught ”for how low they sit in the water.

The two STL files include multiple base sizes (though you don't need to use them).

One STL file has 24 ships (4 different kinds) and three different size bases.

The other STL has 4  different ships and 3 different size bases.
