- Download the boat.stl
- Import into your 3D modeling program of choice. We recommend tinkercad.com
- Modify your boat so that it can hold as many pennies as possible before sinking as compared to the original model.
- Export your new model and add it to 3DprinterOS for printing. You will want it to print in 45 minutes or less and use 30g of filament or less.
