I have a single mechanical component currently saved as an STL that was originally modeled in Blender. I now need it in a precise, fully parametric STEP format suitable for CNC machining. Dimensional accuracy is critical—every hole, edge, and surface must match the existing geometry so the part can drop straight into a CAM workflow without extra tweaks. Please rebuild or convert the file so the resulting .step model is watertight, clean, and free of mesh artifacts. Minor surface smoothing is fine if it helps achieve a solid body, but do not alter any key dimensions. Deliverable • One .step file that opens flawlessly in mainstream CAD packages (e.g., SolidWorks, Fusion 360) and verifies identically against the original STL measurements. Let me know if you need the STL or any reference dimensions to double-check tolerances before you begin.
