About this gig

I provide expert Mechanical Design, DfM Engineering, and Technical Drawing services for every functional Product Prototype and 3D CAD Rendering project. With over 8 years of expertise in Mechanical Design, I specialize in high-precision assets that bridge the gap between initial ideas and final production.


This service is for businesses and inventors who require professional results. I provide DfM Engineering (Design for Manufacturing), ensuring your parts are optimized for CNC machining, injection molding, or sheet metal fabrication.


What This Service Includes:

  • Mechanical Design: Complex assemblies and functional parts.
  • 3D CAD Rendering: Photorealistic visuals for marketing and pitches.
  • Functional Product Prototype: Print-ready files (STL/STEP) for rapid prototyping.
  • Technical Drawing: Precise 2D blueprints for factory production.


I focus on structural integrity and manufacturability. By applying DfM Engineering early, I help you avoid costly errors. Whether you need a Technical Drawing or a high-end 3D CAD Rendering, I deliver professional-grade results.


Deliverables: STEP, STL, IGES, and DXF.
