About
I am a Mechatronics Engineering undergraduate and SolidWorks CAD designer specializing in mechanical components, product design, prototypes, and models prepared for 3D printing.
I can convert sketches, photographs, measurements, and product ideas into accurate 3D CAD models. My deliverables can include STL files for 3D printing, STEP files for manufacturing, editable SolidWorks files, assemblies, exploded views, renderings, and detailed technical drawings.
Through my 3D-printing business, MANEXLAB, I have practical experience designing, preparing, and testing parts using PLA and PETG. This allows me to consider tolerances, clearances, wall thickness, print orientation, assembly requirements, and material limitations—not only the appearance of the model.
My engineering background also includes robotics, mechanical systems, electronic enclosures, reverse engineering, and prototype development. I communicate clearly, follow dimensions carefully, and am available for both one-time projects and ongoing CAD work.
