Beer Pong (Ping Pong) Catapult
thingiverse
Simple design for rubber band powered Ping Pong ball launcher. The arm is designed for the standard 40mm Ping Pong ball. Distance and Power depends on how many rubber bands you use. Any layer thickness Print arm 40% infill for stretcher Base 20%. or whatever your heart desires. A lighter arm will move faster. I left the Pin that goes through arm and Base slightly large so the base wholes need to be drilled out with the closest size bit you have, that way the hole walls are smooth rather than layered.
