Catapult for ballistic experiments.

This launcher boasts a scientific foundation. It showcases the impact on a projectile's trajectory, depending on the angle at which it is launched. By doing so, the launcher can be fine-tuned for its intended purpose. The base structure features a series of holes where an M3 bolt can be inserted to arrest the lever. Simply switching to a different hole adjusts the stopping point. Powered by two rubber bands, the launcher includes a trigger button for effortless firing. It is advisable to print with 100% infill density. A 100% infill results in a sturdier and more robust structure. The components are designed to fit on a 20x20 cm table surface. If your printer has a smaller build area, it is recommended to resize the parts instead of rotating them. Rotating the parts can lead to weaker structures due to the lack of +/- 45 degree layering. The included SCAD files enable users to make modifications as needed.
