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.
