About this service

Have a mechanical product or part that needs to be turned into a clean, manufacturable CAD model? I’m a Mechanical Design Engineer specializing in 3D CAD, mechanical systems, prototyping, and manufacturing-focused design. I can take your sketches, measurements, reference images, or existing CAD and develop them into accurate, parametric models ready for prototyping or fabrication.

**What You’ll Get:**
* Accurate parametric 3D CAD models
* Mechanical parts and assembly designs
* Designs optimized for CNC machining or 3D printing
* STEP, STL, and other required CAD formats
* Design modifications and refinements
* Basic engineering drawings and manufacturing documentation
* Practical consideration of fit, assembly, materials, and manufacturability

I primarily work with Autodesk Inventor and Fusion 360 and have hands-on experience designing and building mechanical systems through robotics, prototyping, CNC machining, and 3D printing.

Whether you have a rough concept or an existing design that needs refinement, I’ll help turn it into a functional, fabrication-ready mechanical design.

Contact me to discuss your project and get started.

Questions and answers

I can work from sketches, measurements, reference images, existing CAD files, or a detailed product concept. The more information available, the more accurately I can estimate the scope and deliverables.

Yes. I consider manufacturing methods, materials, tolerances, assembly, and practical fabrication requirements when developing the design. I can design for CNC machining, 3D printing, and other manufacturing processes.

Yes. I can design individual components and complete mechanical assemblies, including component interfaces, fit, motion, and assembly considerations.

I primarily use Autodesk Inventor and Fusion 360 for parametric mechanical design, assemblies, and prototype development.

Yes. I can refine, modify, or rebuild existing CAD based on new requirements, measurements, manufacturing constraints, or functional changes.

I can provide common CAD formats such as STEP and STL, as well as native Autodesk Inventor or Fusion 360 files when required. I can also create detailed technical and manufacturing drawings with dimensions, tolerances, materials, and other relevant specifications.
