Accurate 3D Model From Photo -- 2

I have a single photo of a plastic art piece that I need translated into a 3D-printable file. The goal is a faithful, one-to-one recreation—every curve, edge, and surface must match the picture without interpretation or stylistic tweaks.

The finished piece will be printed at a large scale (over 30 cm tall), so the mesh has to be clean, watertight, and detailed enough to hold up when enlarged. Please deliver a ready-to-slice STL (OBJ in addition is fine) already set to the correct dimensions shown in the image.

• Deliverable: print-ready STL (and optional OBJ) matching the original design
• Requirements: manifold geometry, no non-manifold edges or intersecting faces, uniform wall thickness suitable for FDM or resin printing
• Scale: over 30 cm exactly as in the reference image

I will supply the reference photo as soon as we start. Let me know if you need additional angles or measurement checks—accuracy is everything on this job.
