Product CAD File Fix & Manufacturing Quote Assistance – Consumer Dispenser

I’m looking for a skilled mechanical/product engineer to help finalize and prepare my product (a paint dispenser) for manufacturing. The Step files are mostly complete, but I need you to:Review and fix broken STEP files (some parts aren’t watertight or quoting properly) • Confirm functional fitment between parts (spout, paddle, handle, wall bracket, etc.) • Apply DFM (Design for Manufacturing) standards • Assist with getting quotes from multiple manufacturers for CNC and injection molding (if feasible) • Help select materials suitable for a soft launch prototype • Advise on best manufacturing method for cost, durability, and quality
