This is a ruler that helps you draw circles, ellipses, Orthonormal coordinate system, parabola, square and dashed lines. It is 20 cm long in total (edges are flush with the first and last graduation). Numbers may be hard to read so I encourage you to print it with two colors (just need a pause at a certain height in your slicer).
Circles are from 2 to 15 cm in diameter and the square is 10cm wide.
I've created it because I didn't want an expensive and bulky ruler. I choose the shapes that I most often use in my studies (in university).
Note that depending on your printer, graduations may be not so accurate.
