Have a mechanical component, assembly, or product that needs to be properly designed and clearly documented? I can help with that. I'm Sameth, a Mechatronics Engineer based in Sri Lanka with 4 years of experience in mechanical design and CAD. I work with engineers, product designers, and small businesses to turn ideas and rough concepts into detailed, manufacturable designs. What I typically work on: 3D part and assembly modeling — designed with manufacturing in mind Technical drawings with tolerances and annotations, your supplier can work from Mechanism design, motion studies, and sheet metal components DFM reviews to catch potential issues before production 3D printing — prototypes and functional parts when needed, in FDM or SLA Tools I use: SolidWorks · Autodesk Inventor · Fusion 360 · AutoCAD I'm SolidWorks-certified, hold a diploma in AutoCAD, and take communication and accuracy seriously on every project — whether it's a single bracket or a full product assembly. Feel free to message me with your project details, and we can take it from there.
