STL-to-STEP Conversion Needed

I have a finished part in STL format (also have OBJ, FBX, and Zbrush) that now needs to move into production. All I require is a clean, dimension-ally accurate STEP file generated directly from the existing mesh—no edits or design tweaks, just a faithful conversion. The final file must open flawlessly in common CAD environments (SolidWorks, Inventor, Fusion 360, etc.) so our manufacturing partners can pick it up without extra work.

Deliverables
• One STEP (.stp/.step) file converted from the supplied STL
• Geometry verified to import into mainstream CAD software without errors or missing faces

If you routinely translate mesh data to solid models and can turn this around quickly, let’s get started.
