This is a simple screw measuring Tool for Metric Bolts and Nuts.
In the middle hole you stick in your screws and push it down to measure the thread, on the right you have the Wrench sizes of standard Metric Nuts and on the left sid you have a Scale for length measurement, all in the size of a credit card! Perfect for your wallet or laying around you workshop.
With a 0.2mm nozzle the Text will be more clean.
