The prompt
A hyper-realistic 3D model of a medical specimen collection cup, focusing heavily on the detailed screw-on mechanism. The cup features a translucent, frosted polypropylene body with a threaded neck. The helical screw threads on the neck must be deeply modeled, sharp, and accurately pitched, with realistic depth, not just a flat texture. The lid is a glossy red plastic cap with vertical grip ribs and matching internal threading. Shown slightly unscrewed to reveal the thread mechanics. Injection-molded plastic look, accurate mechanical topology, PBR materials, macro details on the threads, studio lighting, 8k resolution, 3D asset."
