Bolt and nut caliber

Measurement tool for metric bolts and nuts. This caliber can measure sizes from M4 to M18 and lengths from 6-145mm.

The print has pretty big flat footprint so no brims or such needed. You can pretty freely adjust the printing parameters as you wish to optimize the print time/quality. It doesn't need any supports either.

I printed this just by using the default settings for PETG in PrusaSlicer for my MK3S+ (layer height 0,2mm and infill 15%). It took 6 hours to print with those settings, but as said feel free to optimize the printing time with different settings.
