3D Printer Tolerance Gauges

1.) Print the : 3D Printer Tolerance Gauges 20mm.stl
2.) Test fit the gauges on the test pin.
3.) Determine the closest fitting gauge
4.) Print the file with the closest matching gauge size: 3D Printer Tolerance Gauges Fine 20.## mm

Advanced : If you have Fusion 360 you can edit the parameters for the "test pin" size and when you determine the proper gauge you can edit the "closest gauge hole" expression and then save the "Gauges Fine" component as a STL and print one with new test pin siz
