Hole size tester for 2-3mm

thingiverse

Print this out to test how screws fit with your printer and material of choice to determine the correct diameter needed in your 3D print designs. This is just for 2mm and 3mm hole sizes in 0.1mm increments. The number on the left is the whole number size and the numbers along the top indicate tenths of a mm. Use the same printer profile to print the tester that you will use to print the final design and they should match. Calibrating your e-steps is a good idea too. The numbers are raised so you can color them with the flat side of a sharpie marker to make them stand out, like in the photo. Fusion 360 project file is included if you want to make your own version.
