Channel-set wedding band, 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, as one closed solid. 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. The piece is one closed solid (no holes, no overlapping shells) in real millimetres, so it can go straight to castable resin or wax. Ask your caster whether they want it scaled up for shrinkage. Every stone's seat is cut to its exact shape, and the channel's walls overlap each girdle, as they look once set.

This one, as first shown, is about 4.5 g in 14k gold, 5.4 g in 18k gold and 7.4 g in platinum, measured from the 3D model itself. The table above has other sizes.

A channel protects the stones' edges and leaves nothing to catch on clothes; prongs show a little more of each stone. The prong-set version is the eternity band.

Half covers the top, which keeps it comfortable between the fingers and leaves plain metal underneath for resizing. Full goes all the way round.

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.
