As you can see, both the 2D design and this 3D model consist of one design element that has been rotated four times. If you are into 2D and 3D drawing, borders of different shapes can be formed using this one design element. This 3D design is simple and universal because it can be used to decorate both square and circular surfaces, it can be a frame within which the main motif is found, or it can be a central simple frame representing only a small part of a more complex decoration. You can make a corner design or semicircular design from it .... It all depends on your creativity.
