Based on the idea of the user Sneaks i made a measuring tool for metric screws.
This tool can measure M2-M10 screws with a length of 4-120mm
Printing instructions:
Color change for the letters & numbers
If you dont want to paint the letters you can add a color change with prusaslicer.

Update 06.12.2020
Additional version with raised letters
The author remixed this model.
Mein Werkzeug kann eine Schraubenlänge bis zu 120mm vermessen, außerdem kann es mehr Schraubendurchmesser bestimmen.
