I’m Sharay, a Product Designer with over 7+ years of experience specializing in 3D modeling, 3D printing, STL conversion, and consumer product development. I help startups, inventors, and companies bring their ideas to life, from rough sketches or concepts to production-ready 3D models and technical drawings. My work focuses on creating designs that are not only functional and manufacturable but also optimized for 3D printing, prototyping, and mass production. Whether you're building a mechanical device, a product enclosure, or a printable assembly, I ensure it’s modeled with precision, clarity, and manufacturing intent. Over the years, I’ve designed a wide range of products, including electronics housings, mechanical enclosures, custom tools, wearables, and 3D printable replicas. I also provide services for reverse engineering and mesh-to-CAD conversion, particularly when clients only have STL files or 3D scans and need accurate CAD models from them. Services I Offer: 3D CAD modeling using SolidWorks, CATIA, and Geomagic Design X STL repair, editing, and conversion to solid CAD models Product design for 3D printing, CNC, or injection molding Reverse engineering from scans or reference models Assembly modeling, exploded views, and 2D technical drawings File delivery in STL, STEP, IGES, SLDPRT, DWG, DXF, PDF, and more I understand that many clients come with just an idea, a rough sketch, or a need to upgrade an existing design. I work closely to develop concepts that are production-ready and aligned with your end-use goals. I can also help with design iterations, mechanical fitment, and preparing technical documentation for prototyping or manufacturing. Clients appreciate my clear communication, fast turnaround, and ability to translate vision into professional engineering output. Whether you need just a clean STL file or an entire product designed from scratch, I’m ready to help. Let’s talk about your next project. I usually reply within a few hours.
