CHECK MY PROFILE FOR AN UPDATED VERSION OF THIS RULER (FAR BETTER)

A ruler with 5 circles (dimensions 1/5", 2/5", 3/5", 4/5", and 1") two ellipses, a template for tables/graphs (I use it for shear and bending moment diagrams), and a dotted line template.

I suggest using my gcode, I tuned my slicer settings quite a bit so it should work well. Printed on and Ender 3.

Please posts your makes! It warms my heart to see others using my model (:
