A great tip recommended by a commenter on Thingiverse! Thanks, SPYKE357

"Tip for you and any that use this, open the gauge and remove the little metal part that makes friction on the ruler. This will make the ruler/measuring stick free float so you can rest it on top of the string without having to press down. Much more accurate, give it a try, if you don't like it then you can just reinsert the metal part"
