Remarkable Ruler

A small ruler I made for my reMarkable to avoid any scratches (that could have been made using a real one or any straight object).

I made it to be able to draw straight lines and even measuring some angles when required.
I reduced the thickness so that I could slide it between the tablet and the cover.
It is a bit longer than the actuel width of the screen.

The angles are the "main" ones of the trigonometric circle (0, 30°, 45°, 60° and 90°).
It is also graduated every centimeter

Enjoy!
