Easy Catapult

As soon as I saw Adam-M's Catapult Card I wanted to print it but I soon noticed a problem, it takes 4 hours to print and 40 grams of filament! So I have designed this catapult to be not only half the time, 2 hours, and filament, 19 grams, but also have a powerful performance shooting up to 2 meters.I have also made it as user friendly to build using minimal parts and only requires a repetitively straight forward assembly.
