Minimum Boat
Ladys and Gentleman, I present you:
The smallest craft, capable of caring 2 €.
With a mass of only 0.12 g and a volume of 0.11 ml this little baby is able to carry 8,50 g of pure European money!
But wait, it gets even more crazy: Printed with fine Makerbot ABS you only need 0.0072 € worth of ABS for this 2 € craft! Printing time is 17 m at 0,1 mm layer heigt, that means you can print ships for over 7 € per hour.
How to build:
Print and glue to a 2 € coin.
