I have a product concept that now needs to exist as a precise, production-ready 3D model. The model must be highly detailed, capturing every intricate part so it can go straight to a 3D printer without additional cleanup. Dimensional accuracy is critical, and small mechanical features can’t be approximated or simplified. Here’s what I will provide: • Reference sketches and dimensions • Notes on moving or interlocking components • Any material or tolerance constraints that affect wall thickness or overhangs What I need back: a watertight model supplied in STL (plus the native file from your preferred CAD package—SolidWorks, Fusion 360, Rhino, or similar) that passes standard slicer checks for printability. I’m happy to answer questions about tolerances, fit, or assembly as you refine the design. Once the final file slices without errors and all details are preserved, the project is complete.
