I’ve found it interesting at times when I realize that there are things that are so simple when working in real world scale. One of those things is that you can space a bunch of lines out at 1/8" and print it out and it’s still 1/8" apart. This makes it dead simple to make a ruler or other measuring device. So, you can spend more time decorating them. Here were some we made out of tongue depressors at the Maker Faire to hand out.
I wanted to make something bigger and more decorative so I also made this one out of 1/8" cherry plywood.
I was pretty happy with it until I realized I’d forgotten the “0” line, so I just hit it with a sharpie until I cut a new one (I updated my file to have it ;)).
