Cuban link chain, free 3D model

Yes. There's no account, no watermark and no limit. You can print it, cast it, render it and sell what you make. If you share the file itself, please credit Bling AI with a link to this page.

STL for 3D printing or a casting house: the metal only. 3DM to open in Rhino or Matrix, with the metal and stones on their own layers. OBJ for Blender, KeyShot and most other 3D software. GLB for the web, AR and quick renders, with metal and diamond materials. All of them are in real size.

Yes, as separate closed solids already linked, 0.22 mm apart, so a resin printer makes the whole chain in one go and it moves straight off the plate. For metal, ask your caster before casting a linked chain in one piece; it can also be the pattern for chain made the usual way, from wire.

This one, as first shown, is about 54.2 g in 14k gold, 64.5 g in 18k gold and 88.5 g in platinum, measured from the 3D model itself. The table above has other sizes.

The chain is one closed loop. Cut one link open (in CAD, or after casting), hook on a lobster or spring-ring clasp with a jump ring, and close it again.

It's solid metal, as casting needs, and Cuban links pack a lot of it into every inch. Shop chains often use hollow links to cut the weight, and the price. The tables above are for solid links.

3 to 5 mm reads as a fine everyday chain, 6 to 8 mm as a classic Cuban, and 10 mm and up as a statement piece. For a bracelet, set the length to 7 or 8 inches.

Yes. Make product photos of it opens the piece in our 3D viewer: choose the metal and angle, and Bling AI turns that view into studio and on-model photos. That part needs a free account.
