File Format InformationThe download includes industry-standard formats to accommodate all professional workflows. You will receive the native CAD source format (3DM) for direct editing, the stereolithography format (STL) optimized for 3D printing, and universal mesh formats (OBJ, FBX) for seamless integration into studio rendering environments.

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.
