Manufacturing and ReadinessThis model has been rigorously verified through industry-standard mesh repair protocols. It is delivered as a fully watertight, non-manifold-free, closed solid body. The geometry is completely prepared for high-resolution resin 3D printing and subsequent investment casting. Tolerances, prong lengths, and thicknesses have been strategically calculated to allow for standard metal shrinkage, filing, and final high-polish finishing.
