Jewelry and keychain STL files for 3D printing: pendants, rings, watch links, badges and keychains. They are small, fast prints that make good gifts. Try the gyroid keychain or the owl pendant. Each file is an instant digital download you print on your own printer.Resin printers capture the most detail on small jewelry. On FDM, use a 0.12 mm layer height and slow down to 30 mm/s for clean edges. Make sure the keyring hole is at least 3 mm wide and print keychains flat so the ring loop stays strong. Sand jewelry lightly and add a clear coat or nail polish for a smooth, shiny surface. Use metal jump rings and key rings, not printed ones, so the piece doesn’t snap off your keys.Looking for gift ideas? See our 3D printed gift ideas.
