Catapult for ballistic experiments.

This projectile launcher boasts a strong scientific foundation. It vividly illustrates the impact of angle on the distance a launched object travels, empowering users to fine-tune their setup for optimal results. By strategically positioning M3 bolts into specific holes within the base frame's lattice design, users can alter the lever's stopping point at will. The device relies on two robust rubber bands for propulsion, accompanied by an easily accessible trigger button that simplifies the firing process. Recommended print settings include a 100% infill density, which fortifies the structure and enhances its overall integrity. Once assembled, the launcher should fit comfortably on a standard 20x20 cm work surface. In cases where this space constraint applies, we advise resizing rather than rotating the parts to ensure stability. Rotating could lead to compromised strength due to uneven layering, typically resulting in less than optimal performance.
