Complrtely prepared and tested STL files for printing and 3DM source file for editing and modifying
Both rings are 18mm in diameter. Some dimensions are shown on preview pictures.
Smaller ring volume is 505mm^3
So weight of smaller ring is ~5.1g for sterling silver.
Bigger ring volume is 535mm^3. It made hollowed inside of front. Weight of bigger ring is ~5.4g for sterling silver.
OBJ's were added just to follow some stupid recomendations of CGtrader about better product publishing and placement (that anyway don't works...). OBJ's exported from Rhino source as meshes and as NURBS but not tested. Anyway this model was made for PRODUCTION and was succesfully printed, CNC-machined. Somewhere on Earth satisfied people wearing these rings.
