Fully 3D Printed Catapult

This is a fully 3D printed catapult capable of launching projectiles over 80 feet. The spring is attached to the arm using a hexagon, so you can add more tension by rotating the spring a little more before attaching it to the arm and to the frame itself. If you have any questions, feel free to leave a comment and I'll try to answer them to the best of my ability! Hope y'all enjoy it!
