Thước đo kích thước và độ dài bu lông máy bay AN

After downloading other bolt gauge models, I realized they did not take into account that bolts larger than AN4 have 1/16" longer threaded section, and a dash-number of an AN3 or AN4 is 1/16" shorter than an AN5 or larger bolt. This takes that into account, and also has a diameter gauge for bolt size identification.

Printed with PETG (just happened to have it), .2mm layer height. 10% gyroid infill, and change the top two layers to a contrasting color for the text, or use a permanent marker or paint after printing to add contrast. 

Used a .4mm nozzle and “quality” setting to help the text, though the text might come out better with a smaller nozzle.

Above settings give a 3:01 print on a Prusa Mini.
