perforated metal sheet 3d model

A flat, square, single-layer perforated sheet with a regular grid of small square holes. The sheet is very thin, like paper or sheet metal. The hole pattern covers the entire square without any solid border or frame; the grid lines continue all the way to the edges, so the outermost holes are open at the perimeter. The intersecting strips that form the grid are thin and evenly spaced. The overall shape is a perfect square. The model should be just a flat 2D-like surface with square perforations, not a thick 3D lattice or a framed panel.
