US-Based Product Designer Needed for Novel Consumer Accessory (Concept + CAD)

I am seeking a product designer with strong CAD experience to help develop a novel consumer accessory concept. The project involves evaluating product architecture, developing manufacturable design concepts, and creating initial CAD models suitable for prototyping and manufacturing discussions. The product concept will be shared only with shortlisted candidates. Ideal candidates have experience with consumer products, accessories, injection-molded products, and bringing new physical products from concept to prototype. Deliverables: - Product architecture recommendation - Mounting system recommendation - Folding mechanism recommendation - Rough manufacturing cost estimate - Initial CAD assembly - STEP files - Basic renders
