A simple thread gauge for metric threads, designed to check bolts from sizes M3 to M14. The bolt diameter can be verified using the corresponding holes, and the thread pitch can be checked along the disc’s edges.

Material and print time are minimal, depending on your settings. The tool requires approximately 5g of filament and can be printed in under 30 minutes (with 0.4mm nozzle and 0.2mm layer height). The disc thickness is set to 1.5mm by default, but this can easily be adjusted in your slicer (Z-axis scaling) to suit your needs.
