The author remixed this model.
A 10-inch shelf for the Tiny/Mini/Micro TinyMiniMicro Lenovo 1-liter machines, fitted specifically to the M70/80/90q. Will also fit the M720/820/920, with a flush face but not as tightly around the body. Has holes for threaded M3 inserts in the back, if you want a rear retention bracket.
Dell Optiplex Mini's also fit, but with a 2mm gap on the sides.
