  1. Download the boat.stl
  2. Import into your 3D modeling program of choice.  We recommend tinkercad.com
  3. Modify your boat so that it can hold as many pennies as possible before sinking as compared to the original model.
  4. Export your new model and add it to 3DprinterOS for printing.  You will want it to print in 2 hours or less and use 30g of filament or less.
