Float mark 1

This model is designed similar to an inflatable boat, to avoid a float filling with water the bottom is opened and seals agents the water creating an air pocket. The cut outs around the outer wall are so the air pocket forms above the coins so it is more stable like a sailboat keel. Max carrying weight is 11 American pennies. The boat is 85 mm at its widest point.
Problems:

1. Carrying weight was not good.
2. The coin holes were too small.
3. Unstable
4. Long print time 165 minuets
