Marking gauge (metric)

I designed this flexible marking gauge. It fits to a mechanical pencil with all diameters of pencil mines (they get centered automatically). Because of its flexibility complicate mesauring tasks shoul be no probeme. Step is 1mm to make precise markings. Maximal mesauring lengs is 145mm. Center line is only for quicker reading off.

Print it with 0,1mm to get the numbers in good quality.

Check also my other measuring tool ;-)

Here is a imperial version with inches:
