I already have a finished model in Blender and now need it rebuilt as a clean, watertight STEP file ready for manufacturing workflows. Please keep the geometry exactly as it is—no extra dimensions or tolerances are required at this stage—just a faithful translation that opens flawlessly in any standard CAD package (e.g., SolidWorks, Fusion 360, or similar). The deliverable is a single STEP file that mirrors the original mesh, with surfaces properly joined and free of non-manifold edges so machinists can begin tool-path programming immediately. If minor tweaks are essential for a solid body, feel free to implement them, but the overall form, scale, and detail must remain intact. Kindly let me know your typical turnaround time and any questions you may have about the Blender source before you dive in.
