Fiverr • Freelance

Aug 2024 - Present • 2 yrs 2 mos

I specialize in Injection Molded Plastic Product Design, SolidWorks CAD Modeling, Consumer Electronics Enclosure Design, and Design for Manufacturability (DFM), helping product developers, startups, and manufacturers transform concepts into functional, production-focused plastic components. My work focuses on developing accurate 3D CAD models, optimizing plastic part geometry, improving assembly functionality, and preparing designs for prototyping and injection molding. My key responsibilities include: Injection Molded Plastic Design: Developing plastic components with appropriate wall thickness, draft angles, ribs, fillets, and mold-release considerations. SolidWorks CAD Modeling: Creating precise 3D parts, multi-component assemblies, and detailed product designs. Electronics Enclosure Design: Developing custom plastic housings, PCB mounting supports, connector openings, and internal component layouts. Snap-Fit & Mechanical Features: Designing snap-fit clips, screw bosses, hinges, fastening systems, and assembly interfaces. DFM Optimization: Reviewing product geometry for injection molding, CNC machining, 3D printing, and manufacturing efficiency. Manufacturing Documentation: Preparing STEP/STP CAD files, dimensioned 2D technical drawings, and mechanical design specifications. Product Prototyping: Refining designs based on functional requirements, component fit, assembly clearances, and prototype feedback. I focus on balancing mechanical functionality, durability, manufacturability, and cost efficiency while maintaining clear communication throughout product development. My goal is to help clients develop reliable plastic products that can progress smoothly from concept and prototyping toward manufacturing.
