Convert Image Into 3D Printable OBJ

I need a clean, watertight .obj file generated from a single reference image so I can send it straight to my 3D printer. For this pass I only care about the basic shape and structure—no textures or intricate surface details. Any overall scale is fine; I’ll resize it later in my slicer.

Please model with standard 3D-printing guidelines in mind: manifold geometry, correct normals, and no non-manifold edges. A sensible polycount is welcome but don’t over-optimize.

Deliverables
• OBJ file ready for printing (MTL optional)
• Quick screenshot or short turntable for pre-approval
• Version without foot

Let me know which tool you prefer (Blender, ZBrush, Fusion 360, etc.) and how quickly you can turn this around. Fast, clean, and print-ready is the goal; more work will follow if this one runs smoothly.
