Mine sagged under its own weight so replacing it in acrylic was necessary. Make sure to use 6mm or thicker acrylic to avoid softening from the heat of the heated bed during longer prints.
The DXF file can be used directly with a laser cutter, instructions on how to export to DXF from the OpenSCAD model are included in the scad source code.
