Title: Product/Industrial Designer Needed to Refine Premium Stainless Steel Tumbler (Existing Design Provided) Description: I already have an initial 3D design for a small 12–14 oz stainless steel insulated tumbler. I am looking for a skilled industrial/product designer to refine the existing design, improve its uniqueness, and prepare it for manufacturing. The tumbler’s overall silhouette is defined, but it needs a more unique, premium, minimalist identity, with special attention on the lid, which must become a key differentiating feature. Project Scope 1. Tumbler Body Refinement Improve proportions, curves, and surface transitions Enhance the premium/minimal aesthetic Maintain a sleek, seamless exterior Make the form feel more distinctive while staying subtle 2. Lid Redesign (Top Priority) Combine visual uniqueness with simple mechanics: Redesign the lid into a visually unique, signature element of the product while keeping the mechanism simple (twist-lock + flip tab). The external geometry should be refined, minimalist, and premium, clearly differentiating it from competitors. Internally, the functionality must remain robust, minimal, and easy to manufacture. Lid requirements: Twist-lock / threaded connection Flip-tab opening Full silicone gasket Must be leak-proof Mechanism must stay intuitive and minimal Aesthetic must look refined and high-end 3. Manufacturing Optimization (DFM) Prepare final CAD files for stainless steel (304), PP/Tritan, silicone Ensure dimensions, tolerances, and clearances work for vacuum-insulated double-wall manufacturing Simplify components where possible 4. Deliverables Updated CAD files (STEP, IGES, or SolidWorks/Fusion) Exploded view of lid mechanism Design improvements & small iterations Optional: high-quality 3D renderings Optional: manufacturing-ready package Ideal Designer Industrial/Product Design background Experience with insulated drinkware, bottles, tumblers, or consumer products Strong sense of minimalist, premium, modern aesthetics Comfortable designing for stainless steel + injection molded plastics Understands leak-proof mechanisms, threads, gaskets, and simple lid systems Able to balance visual design, mechanical simplicity, and manufacturability To Apply Please include your portfolio, specifically: Drinkware Consumer products Minimalist premium objects Products with mechanical components (lids, seals, threads)
