I am presenting a 3D model of an engagement ring, fully optimized for 3D printing and casting:

Central stone: 5 mm round topaz, designed for a secure prong setting.

Side stones: 40 pieces, 1.25 mm each, arranged in elegant wavy tracks along the shank.

Ring size: 17.00 mm (equivalent to US size 15).

Top width: 5.00 mm.

Profile height: 5.74 mm from the finger.

Design features:

The shank and the head (stone setting) are modeled as separate parts for easier casting and post-processing.

Optimized geometry for clean casting without defects.

Polished surfaces and support-friendly design.

Available formats: 3DM, STL, OBJ, MTL, FBX.

Perfect for jewelry manufacturing and ready for your creative projects!
