My daughter is having a Moana themed birthday party and asked if we could print models of her boat for all the kids. Since I didn't find one I like I decided to make this one instead. The parts are designed to press fit together to make it easy to assemble, but a little bit of hot glue will help hold it together.
And yes it floats, and makes a pretty good bath toy.
The profile has one plate with a complete boat, and three plates set up to mass produce them since I needed 40 total for the party.
