A reference board to measure how deep different laser engraving speeds and percentages are. The notches are big enough for standard vernier calipers.
I just used some scrap for this prototype, so that's why it only has four sets of three percentages on it.
(I was making some braille name tags and there is a regulation height for the braille dots to be)
