mini catapult 3d model

Simple compact 3D model of a small catapult designed to launch a LEGO minifigure. The design should be clean, minimal, and realistic, similar to a basic triangular-frame catapult. Include a sturdy triangular base, a single throwing arm with a pivot, and a small cup sized for a LEGO minifigure. Add a simple printed flexure or bending arm for energy storage (no complex mechanisms). Include a basic locking and release trigger that is easy to understand and not overly complicated. All parts must be fully 3D-printable with no external components, using only printed plastic. No screws, no metal, no rubber bands. Keep the design compact and proportional, fitting within a 150mm cube. Avoid excessive details or unrealistic shapes. Focus on a clean, functional design that looks like a real simple catapult. Style: matte plastic, smooth surfaces, minimalistic engineering design.
