This is a 15cm/6inch ruler that you must print with a 0.2mm nozzle. It is 1mm thick and have two colors to make sure you see the lines. The precision is down to the millimeter in metric and down to the 1/16 of an inch in imperial.
crazy how hard it is to find metric imperial tools ...its crazy living in a country like America that has increasingly both... and yet they barely teach us imperial anymore lol so it's so confusing, like I can't even find metric m3 screws anywhere in american hardware stores that aren't 2 dollars per screw or bolt lol its freaking insane , like I'd be supeised if tools.wer3nt just made illegal in the future
