Ruler with circles and logarithmic scale
thingiverse
Three different rulers for different needs! 1) Double sided ruler in centimeters; 2) an asimmetric one but with a 90 degree angle; 3) the same ruler as (1) with a logarithmic scale. All of them have circles of different sizes. I have designed this for myself but it turned out to be very useful to other people too, so I decided to upload it. If you need something more specific, you can leave it in the comments and I might make another version of this ruler.
