Centimeter - Inch card

A friend asked me to do this card, he has a few bolts and nuts that are in inches and wanted to know what wrench has to use with one tool, so i made this.

I printed this in 2 colors, has the numers carved into the print, and it's tight, so if you have problems with the print being in somme part smaller, scale it 0.50% more to solve this problem.
