winged square frame 3d model

Create a 3D sculptural square frame (outer size 14x14cm, inner hole 10.1x10.1cm) that looks as if angel wings are wrapping around and emerging from the frame structure. The wings should have smooth, organic forms and detailed feathers, as if they are protecting or embracing the center. Keep the geometry clean and suitable for 3D printing or Blender (.STL or .OBJ format). The frame should feel slightly ornamental but minimalist, with the wings partially integrated into the structure.
