Ship lego-compatible

My 6-old son often plays lego in bath. He missed the true ship sailing on water -not sinking - using his bricks and figures.
I measured pins on Lego bricks and.... print a ship:)
Son is very happy now. Ship is stable on water.

I was afraid about water getting inside infill thrugh small gaps among PLA layers.
I read the acrlic spray is good for cover it.
I bought a nice gold color and paint 2 layers.
After 30 min in water the weight increase from 84 to 85g including small water drops on it.
Great result! Ship is waterproof.

Due to size print was at 45 deg table diagonal.
Print took 11h on Ender 3 v2.
