Hi, I have made a set of 3 size gauges with holes ranging from 2mm to 10.9mm in .1mm increments which I use to work out the size of holes in models to allow magnets, bolts, screws nuts, etc to fit snugly as every printer gives slightly different results you can't always rely on taking measurements.
I've included 2 sets of models, one with the text inset for any printer and one with the text flush for printing on a Bambu AMS is multicolour. If you're printing these in multicolour they print better with the text facing down on the build plate.
