I already have a collection of STL files—rings, necklaces, bracelets, and a few one-off pieces—and I need them taken from “good” to “production-ready.” The goal is to use these files for high-quality visualization and functional prototypes, so every facet must read beautifully when rendered or printed. Here’s what I need sharpened up: • Details & engravings that currently look soft or uneven • Overall shape and proportions so each model feels balanced on screen and in hand • Textures and finishes that will translate convincingly in photorealistic renders You’re free to work in Rhino, MatrixGold, ZBrush, or whichever CAD sculpting environment you prefer, as long as the final deliverable comes back to me in clean, watertight STL (along with the native file if possible). I’ll supply the existing models plus reference photos showing the level of crispness I’m after. Once each file is updated, a quick viewport screenshot and a low-res test render will help confirm the improvements before we sign off.
