Hummingbird medallion for casting 3D print model

The hummingbird BAS-RELIEF medallion for casting is made as a single element. I set the size to 45mm in diameter. The model has a high resolution, and you can change the size as you wish.

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.
