Step Block Gauge Keychain

Hey! This is my "first" design that I thought was useful to some degree and the first design I have uploaded to the interwebz.

It's designed to give you an idea of width, height, or depth of something small. Sometimes I find myself needing to know... What's the size of that hole, or what's the gap space here on this drawer? Instead of constantly using a tape measure, I decided to build this keychain tool for quick and easy access.

Feel free to remix as you wish! I think it would be cool to print this in multiple colors to show a quick reference to commonly used measurements (1/4, 1/2, 3/4) or add text along each step.

The steps are in 1/16ths and measure up to 1" either direction.
