round pendant 3d model

Add a small integrated loop hole at the top for a necklace chain, keeping it clean and minimal. On the front face, engrave a delicate September birth flower design in the center. The engraving should be fine, elegant, and shallow enough for jewellery casting, with clear floral line details. Keep the back of the pendant flat and plain. The overall design should be simple, refined, and suitable for 3D printing and silver casting.
