Convert Design Image to STL

I have a set of reference photos and precise measurements for a small product that includes a handle, engraved or embossed decorative flourishes, plus strap attachment points on both sides. I need a clean, watertight, manifold 3D model from these references and dimensions, delivered as a print-ready STL.

Accuracy is essential—the finished file must reflect the exact measurements I supply so I can drop it straight onto a printer build plate without additional tweaks. If you prefer to model natively and then export, feel free to send an optional STEP file alongside the STL for future edits.

Deliverables
• Print-ready STL (correct scale, watertight, manifold)
• Optional STEP for future modification
• Optional physical sample if you also offer printing and shipping—let me know your capability and cost, though the digital file alone fulfils the brief.

When you respond, please link to a few examples of similar work you have produced—especially pieces that show fine decorative detail and functional elements like handles or attachment fixtures.

The project budget is firm; by applying you confirm your acceptance. I look forward to collaborating and seeing your portfolio.
