Trebuchet, or counterweight catapult
thingiverse
Three parts. One is the frame, one is the swing arm, and one is the set of moving parts. Has been printed on a MiniFactory and works almost out of the box, some filing or sanding requred. I created a new swing arm, but the one in the MOving parts print set should work just as well.
