NEED PRODUCTION-READY, FUNCTIONAL CAD MODELS OPTIMIZED FOR 3D PRINTING? Coming from a background in enterprise software engineering (with an MS in Computer Science), I bring a developer's mindset to 3D CAD design. I don't just sculpt shapes—I engineer functional, parametric systems. My main focus is creating clean, reliable models built specifically for FDM printing. I know firsthand how critical printability, tight tolerances, and mechanical fits are, so I design parts that work perfectly right off the build plate. I treat CAD design like writing production-grade code. When you work with me, you get: ▪ TRUE PARAMETRIC DESIGN: Models built so you can easily tweak and update dimensions by changing a few simple values. ▪ CLEAN ARCHITECTURE: A tidy file structure and a logical, easy-to-read model history timeline. ▪ END-TO-END SUPPORT: I don't just hand over a file. I am happy to advise on slicing settings, material choices, and print optimization to make sure you get the best physical result. I publish my independent work under the "Void to Solid" name (feel free to check out these models in my Upwork portfolio). If you have a sketch, a technical requirement, or just a rough idea in mind—feel free to reach out. Let's discuss how we can bring it to life.
