I provide mechanical CAD design and 3D modeling services for manufacturing, product development, and rapid prototyping. My work includes converting STL mesh files into editable STEP CAD models for reverse engineering, transforming 2D engineering drawings into accurate 3D mechanical models, and repairing STL mesh errors such as holes and non-manifold edges for 3D printing. I also design custom sheet metal enclosures and prepare STEP files, DXF flat patterns, and fabrication drawings. I focus on dimensional accuracy, clean geometry, practical design, and delivering CAD files that meet each client's project requirements.
