Classic Flat Band Wedding Ring — 4x1.8mm | 3D Printable CAD File (3DM, STL, OBJ) — Sizes 48–58
*** All Files Types Include
Description
This listing offers a timeless Classic Band wedding ring, designed with a clean, flat-top profile and gently beveled edges that catch the light from every angle. With a width of 4mm and a thickness of 1.8mm, the band strikes a balanced, comfortable proportion suitable for both men's and women's wedding or engagement bands, stacking rings, or simple everyday statement pieces. The minimalist silhouette makes it a versatile staple design that pairs beautifully with solitaires, eternity bands, or can be worn entirely on its own. The design is presented in gold, rose gold, and white gold/silver renders to demonstrate its adaptability across different finishes and metal tones, giving buyers a clear preview of how the final piece will look in their metal of choice.
The 3D model was built using professional jewelry CAD software (Rhino-based Matrix workflow), ensuring accurate, manufacture-ready geometry with clean, watertight topology and no mesh errors, non-manifold edges, or overlapping faces. The file has been engineered as a solid, closed volume specifically optimized for jewelry production pipelines, including wax 3D printing, resin printing, and CNC milling. Technical renders included in this package show orthographic views, cross-section thickness (4.00mm profile height reference and 1.80mm band thickness), and multiple ring sizes rendered independently for size verification before purchase. The design is pre-built and tested across a full size run from European size 48 to 58, so the geometry has already been validated for consistent wall thickness and structural integrity at every size in that range, minimizing the risk of print failure or distortion.
This CAD file is fully prepared for direct manufacturing use, whether through lost-wax casting, direct metal 3D printing (DMLS/SLM), or CNC production. Because the model has been verified for scalability, jewelers and manufacturers can confidently resize it further outside the pre-tested range using standard ring-sizing workflows without compromising the band's proportions. The file is compatible with all major metals used in fine jewelry production — including 9K, 10K, 14K, and 18K white gold, yellow gold, rose gold, and sterling silver/continuum silver — and reference gram weights for each of these metal types across multiple sizes are included to assist with costing, quoting, and casting preparation. This makes the file immediately usable by jewelry manufacturers, casting houses, and independent designers alike.
For sellers and marketplace use, this file is ideal for 3D print shops, jewelry designers, Etsy/CAD marketplace stores, and manufacturing studios looking to expand a catalog of ready-to-produce wedding band designs. It is supplied in multiple industry-standard formats — 3DM, STL, and OBJ — ensuring broad compatibility with CAD software (Rhino, Matrix, RhinoGold), slicers for resin/wax printers, and general 3D modeling or e-commerce preview tools. Its classic, gender-neutral styling gives it broad commercial appeal and repeat-sale potential, making it a strong addition to any digital jewelry asset library, print-on-demand catalog, or manufacturing-ready design collection.
