I can think of a good possibility: a tool used for pressing the rubber splines into aluminum screen doors. You'd have to replace the wheel with one of your own dimension, after 'scalloping' it on a wheel or with a file, so you'd get periodic impressions and skips. Use a straightedge for a guide. Be a lot of work for the first one. Obviously, you'd need to do the rolling on a semi-hard rubber pad or a piece of soft wood.

A couple of ideas. Take some metal window screen. You can distort it so that it forms a diamond pattern. Epoxy it to some plastic or metal flat stock and trim to size. Also some of the craft stores carry expanded metal mesh (aluminum) in various sized diamond patterns which will also glue to flat stock.
In Australia we have a 'dampcoarse' moisture proof for laying under walls in building.
It is thin black plastic with a fine embossed texture that from memory has a diagonal aspect to it.
It could be a reasonable approximation.
You may have the same in the US of A.
