A minimalistic 3D model of a standing astronaut figurine, optimized for 3D printing. The figure stands upright, arms close to its cylindrical body, with legs slightly apart for a stable, flat base. Its smooth, low-poly surface suggests a clean, stylized aesthetic, devoid of intricate textures. The helmet features a simple, flat faceplate, and a small, integrated backpack sits flush on its back. The overall form is solid and robust, designed as a single, support-free piece, likely in a matte white or light gray plastic.
