Is this 3D model really free?

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.

Which file should I download?

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.

Is it ready to print and cast?

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.

Will it fit under my engagement ring?

Point the V toward the head and set the depth to clear its basket: 2 to 3 mm suits most solitaires. For a smooth arch instead of a point, see the curved wedding band.

Can I make product photos from the model?

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.

Chevron ring, free 3D model

Q: How much does a chevron ring weigh?

This one, as first shown, is about 2.3 g in 14k gold, 2.8 g in 18k gold and 3.8 g in platinum, measured from the 3D model itself. The table above has other sizes.

A slim band that dips into a V on top: a stacking ring on its own, or a wishbone band that nests under an engagement ring. Set the size and the V, then download it. Free, with no account.

STL: the metal only, ready for a slicer or a casting house. 3DM opens in Rhino and Matrix with metal and stones on their own layers. OBJ and GLB include the stones. All in real size.

The model

What you're downloading

Shape: the top bends 3 mm along the finger into a V, its arms straight, easing back into the band.
Band: 2.0 mm wide and 1.6 mm thick, flat with softened edges.
Sizes: US 3 to 13 in half sizes, each built to its exact inside diameter (see the ring size converter for UK, EU and JP sizes).
Files: built in your browser when you click, exactly as you set it. STL, 3DM and OBJ are in millimetres (STL and 3DM Z-up); GLB is in metres, as the format requires.
