The OWL BAS-RELIEF medallion is made as a single element. I set the size to 50-55 mm in diameter. The model has a high resolution, and you can change the size as you wish.Please note that the model has two options with and without a hanging eye.
besides the medallion, you can serve both as an independent element of decor, and in combination with other elements, decorating them. It can be cast for a brooch
Model geometry is mesh (polygonal),this is not a Nurbs geometry.It is designed for printing and casting and technically cannot be converted to NURBS geometry.
