I already have a finished OBJ of a new jewelry piece and simply need a few touch-ups before sending it to the printer. Using Blender, please: • Tweak overall proportions and key measurements so the piece meets production tolerances. • Refine a couple of small surface areas for cleaner lines and better visual balance, while preserving the existing style. • Remove any stray geometry, close holes, and confirm the mesh stays watertight and correctly scaled for 3D printing. Deliverables: • Updated OBJ, plus an optional STL. • Clean, print-ready mesh that passes basic manifold checks. The work is small but time-sensitive—I’d like the revised file ASAP. If this goes smoothly, I’ll have more designs coming up in my jewelry line and would love to work with you again.
