classic floppy disk 3d model

Create a highly detailed 3D model of a classic 3.5-inch floppy disk. The floppy disk should have a square shape with slightly rounded corners and a rigid plastic body. The main body is dark matte plastic (black or dark gray), with subtle surface roughness and realistic wear. At the top, include a metallic sliding shutter with a brushed aluminum texture. The shutter should look slightly reflective with fine scratches and realistic shading. In the center, add a rectangular label area with a light gray or off-white color. The label should include: * thin horizontal lines for writing * a small "INDEX" text in uppercase * slightly worn edges and subtle paper texture Include small details: * two square holes at the bottom corners * a central circular hub opening under the shutter * a small arrow embossed in the plastic indicating insertion direction * slight bevels on edges Use realistic PBR materials: * plastic (roughness ~0.5–0.7) * metal (low roughness, high reflectivity) * paper label (slightly rough, l
