This is a small ruler for drawing circles. Available sizes are: 1, 3, 4, 5, 10, 15, 20, 25, 30, 35 and 40 millimeters of diameter. It is great for fast drawing where precision is not the most important. It can be customized using OpenScad for making personal circle sizes.

Hahah thank you, I am glad some people like the Circular Ruler. I thinl I will continue with the 3rd version of this ruler wich has some better features. If anyone has an idea of how could be better, please let me now :)

Circular ruler is an interesting name. Draftsmen called these circle templates (though the design was different). There were also templates for ellipses (if you didn't want to fake it with 4 circular arcs) and other commonly drawn shapes. For example, architects had templates for doorways and such. I wonder if I still have my templates packed away somewhere.

I have all of those templates. I was probably one of the last students to get a chance to cover at least some traditional board drafting as part of my education. I can't argue with having a compact all-in-one tool like this though. Maybe I'll take the liberty of drawing up some doorway templates
