This is a simple catapult design that requires three parts and a rubber band. There is the frame section, the catapult arm and the projectile. The rubber band loops around the catapult arm and then ties into the catapult frame. The arm is pushed up from the bottom into the fram for a snug fit.

Print settings

This was printed in ABS with 3 layers and 15% infill to make it strong enough to withstand many firings of the catapult. No raft was required but minimal supports were used in some areas.
