This ring is available as a 3D model in STL and OBJ format for 3D Printing.
The default ring size is 6 (United States size) meaning it has an internal diameter of 16.51 mm (the model can be scaled to any size before 3D printing).
It is recommended to use a U.S. Ring Size Chart to find out the correct size of the ring and scale the model accordingly to match the desired internal diameter before 3D printing.
If you have any question about this model or any project you have in mind just message me.
