I’m looking for an experienced CAD engineer or product designer to take my existing 3D design files and rebuild them properly from scratch, ready for production in metal.
Background • I designed all parts myself and have already validated the functionality by 3D printing and physical testing • Everything works, but the CAD files are crude and not production-ready • Tolerances are largely guesswork • Parts were developed iteratively by adding and removing features, so many models are a hodgepodge rather than clean parametric designs
What I need • Recreate all parts cleanly in a professional CAD system • Apply sensible, engineering-grade tolerances suitable for CNC machining in aluminium • Produce fully constrained, parametric models • Assemble parts where appropriate to check fit and function • Deliver clean STEP (STP) files suitable for manufacture
Workflow • I would want to 3D print the rebuilt parts first to validate everything before committing to metal • Expect some iteration after first review/print • I can supply existing STL/STEP files, photos, and functional explanations
Ideal candidate • Strong mechanical CAD experience (SolidWorks, Fusion 360, Inventor, Creo, or similar) • Comfortable designing for CNC machining in aluminium • Able to think like an engineer, not just redraw geometry • Experience rebuilding rough prototypes into production-ready designs
Please reply with • Brief overview of your relevant experience • CAD software used • Examples of similar “prototype to production” work
This is a serious engineering tidy-up rather than a simple file conversion, and I’m looking for someone who enjoys turning working prototypes into elegant, manufacturable designs.
Next steps Once I’ve reviewed responses and shortlisted suitable candidates, I will ask for a simple NDA to be signed before sharing any detailed files, drawings, or samples.
