I really liked the idea from Boogie for screw measuring/sorting helper but decided to design my own with some of his approach in mind.

Little printing tip for anyone - just print the two top layers or the 3rd layer from top different colour from the rest and you've got coloured letters. (Use filament change or even pausing the print and manually changing the filament will work.)

FEATURES

• size of a credit card so you can put it in your pocket or a wallet
• screw sizes M2 - M12
• screw length 0 - 84 mm
• uses less filament, is faster to print but still working great

Note: This is reupload of my original design from Printables.
