camera lens 3d model

Create a realistic 3D model of a reusable travel cup designed to look exactly like a professional DSLR telephoto camera lens. The exterior should feature textured rubber focus and zoom rings, engraved focal length markings, switches, metallic accents, and a matte black finish with realistic proportions. The cup should include a removable lens cap that functions as the drinking lid, snapping into place like a real lens cap so the cup appears identical to a camera lens when closed. The interior should be smooth, food-safe stainless steel or BPA-free plastic with a 400–500 mL capacity. Include a hidden leak-resistant drinking opening in the lid while preserving the authentic lens appearance. The base should resemble a real lens mount while remaining stable on flat surfaces. Use clean topology, PBR materials, high detail, realistic textures, and production-ready geometry.
