Bolt size tester
thingiverse
With this tool, I can quickly test a bolt for its diameter and confidently confirm that it will fit after 3D printing. The vertical embossed lettering in my photo, which was painted to highlight the feature, displays the diameter (in millimeters) of each center hole. Meanwhile, the horizontal number indicates the diameter (in millimeters) of the inset, providing valuable information if you plan to recess the head. I deliberately omitted the first 5 holes from the depth chart, as they are set for a 3mm deep recess. The remaining holes have a deeper recess of 5mm. To conserve length and make the design more efficient, I skipped over some larger numbers that I don't commonly use.
