Radius Gauge

thingiverse

A precise gauge measures in- and outside diameters from 0.5mm to 5mm, incrementing in 0.5mm increments.\r\n\r\nEach dot corresponds to the diameter in mm, with clockwise movement for inside measurements and counterclockwise for outside diameters.\r\n\r\nHalfway points are unlabeled, but 2.5mm falls between two and three dots, indicating a clear reading.\r\n\r\nThis gauge works exceptionally well under backlighting conditions.\r\nProper alignment yields accurate results, as seen in the image with a measured diameter of 4.5mm, while misalignment leads to errors, illustrated by the 3.5mm measurement.
