Exact STL-to-STEP Conversion

I have a single STL part that now needs to live in my parametric workflow, so I’m looking for someone who can reproduce it as a solid STEP model. The brief is simple but precision-driven: the new CAD must be an exact geometric match to the current mesh, including every curve, fillet, and cavity. Please keep the topology watertight and organised into logical bodies so I can open it immediately in SolidWorks or Fusion without repair work. Deliverable: one clean, fully solid STEP file that mirrors the STL one-to-one. If you’re comfortable with reverse-engineering from mesh data and have done tight-tolerance conversions before, you’ll find this a straightforward task. I’ll send the STL as soon as we start and will verify the finished file by overlaying it against the original mesh, so accuracy will be the key acceptance criterion.
