Spring Fling Catapult | No Support

Launch ping pong balls with precision using this improved catapult design.

This fully 3D printed catapult features an easy-to-press roller trigger, print-in-place bearings, and guided tracks for consistent, accurate throws. The two-piece trigger design with integrated roller makes firing smooth and effortless compared to the original version.

Print-in-place bearings on both the arm pivot and spring attachment points ensure reliable performance and repeatable accuracy. The molded tracks keep the ping pong ball perfectly positioned every time, so your shots land where you aim. Everything snaps together—no screws, bolts, or additional hardware needed.
