This CAD model presents a classic curb link chain, pre-arranged and supported on a production-ready sprue system. The chain consists of uniformly sized oval links that are twisted and flattened, creating the characteristic interlocking curb pattern with a smooth outer surface. The entire assembly is designed for efficient 3D printing and subsequent lost-wax casting, with the ladder-style sprue frame ensuring stability during the printing process and providing a straightforward path for metal flow during casting. The file is optimized for producing finished chain lengths for bracelets or necklaces with minimal post-processing assembly.If you need to change the size or anything, message me for help. Other sizes and formats can be fabricated—just let me know what size you want. All bugs are checked and fixed. STL file is healed and ready to prototype. After-sale modifications are free within 2 business days.
