I have been racking my brain for months trying to deal my prints always being about 0.2 mm outside to outside or so bigger and hole diameters around the same smaller than what the CAD/STL dimensions are.  This doesn't always matter but for designs that need to fit real world dimensions it can be an issue.  Ideally all parts printed would be the correct dimension for holes and outside dimensions as designed in fusion 360 and allowing the design to be used for 3d printing and other real world uses
