Catapult
thingiverse
Wow drinkers, show off your skills by getting that floating widget without injury. Non-drinkers, amaze the kids with math as you measure projectile diameters using shadow lengths and light sources. The catapult's throwing power is based on infill solidity set during printing time, like 0.3 in the video demonstration, thanks to Igor!
