Looks like that Adafruit ruler is a branded version of the PCB rulers that are all over eBay. They all have the same design with the phrase "one PCB to RULER them all" on the back.

The Adafruit ruler is open source (https://github.com/adafruit/Adafruit-PCB-Ruler) - I suspect the eBay ones are clones of it.
