15 cm ruler with mm function (Accurate)

There are very few measuring tools online without mm function for some reason, so I made my own.

Ruler marks are 0.5 mm high with a ruler thickness of 3 mm. It is possible to print the ruler 2 mm or even 1 mm, however, the ruler will be extremely flexible and does not feel strong at all.

Note: Black markings are drawn on with permanent marker for simplicity. I do not recommend pausing the print to change filaments to mark the numbers and notches in a different colour as testing has resulted in all sorts of issues.
