I have a finished AutoCAD model of a 3D-print part and I need it exported to a single, clean STEP file. The part will be printed in plastic and used as a functional prototype. I’ll supply the original DWG; you return the STEP (.stp) ready for additive manufacturing. If you spot any issues that could compromise printability—thin walls, non-manifold edges—let me know before final delivery so we can adjust quickly. Deliverable: • One validated STEP file that opens error-free in SolidWorks or Fusion 360. Thank you in advance for handling the conversion with care.
