Justina B.

I help startups, manufacturers, inventors, and engineering teams turn product ideas, sketches, and technical requirements into accurate, manufacturable 3D CAD designs.

My focus is on creating mechanical designs that are not only visually complete but also functional, practical, dimensionally accurate, and ready for prototyping or manufacturing.

🔧 Mechanical Design & CAD
- 3D part and assembly modeling
- Mechanical component and mechanism design
- Parametric CAD modeling
- 2D engineering and manufacturing drawings
- GD&T, tolerances, fits, and dimensions
- Exploded views and assembly documentation
- Existing CAD modification and optimization
- Reverse engineering from drawings, photos, or physical parts

🏭 Product Development & Manufacturing
I can support projects from initial concept through production-ready design, including enclosure design, sheet metal parts, machined components, injection-molded products, brackets, housings, mechanisms, fixtures, and custom mechanical assemblies.

I consider DFM/DFA, material selection, manufacturing processes, assembly methods, tolerances, cost, and serviceability throughout the design process.

💻 CAD & Engineering Tools
Experienced with SolidWorks, Autodesk Inventor, Fusion 360, AutoCAD, Creo, and other CAD workflows, including STEP, IGES, STL, DXF, DWG, and native CAD file preparation.

🎯 What You Can Expect
My approach is based on understanding how the product will actually be manufactured, assembled, and used. I communicate clearly, incorporate feedback efficiently, and maintain organized CAD files and documentation throughout the project.

Whether you need a single mechanical component, complex assembly, product enclosure, prototype, manufacturing drawing package, or complete product design, I can help take your concept from idea to production-ready CAD.

Let’s turn your concept into a precise, functional, and manufacturable design.
