Elegoo Gcode to STL/STEP Conversion

I have 4-5 print-ready Gcode files that were sliced in Elegoo Slicer for an Elegoo machine. I now need the underlying geometry extracted and rebuilt into three neutral formats—STL, 3MF and STEP—so I can load the models on my Bambu Lab X2D and any other printer I might add later.

What matters most is that each converted file opens at exactly the same scale it shows in Elegoo Slicer. I also want the overall quality of the surfaces preserved; minor slicer-specific items such as support definitions or layer instructions can be discarded if they interfere, but the final mesh has to be clean, watertight and dimensionally faithful.

Deliverables
• For every original Gcode (8-10 total): one STL, one 3MF and one STEP file
• Quick summary sheet noting the original file name, target scale checked, and any corrections you performed

Acceptance Criteria
1. When I import the new files into Bambu Studio or PrusaSlicer, the dimensions match the originals within ±0.1 mm.
2. No non-manifold edges or mesh errors are reported.
3. STEP files open in Fusion 360 without missing surfaces.

If you’ve previously reverse-engineered sliced Gcodes or generated clean CAD/mesh models, this should be a straightforward task. Let me know your workflow and estimated turnaround and we can get started right away.
