Kids height Ruler

Good effort ! interesting you used inches. Like you I always draw it in CAD first, that way you can see what the outcome is likely to be, it's easy to later modify, you have the design for when other people want one too, and with their name on it
Edit: I lost my marbles a bit there thinking those numbered graduations were inches instead of feet, it's becasue it looked like a 'blown up' ruler.
