Radius/Diameter Gauge

thingiverse

These tools facilitate measurement of radius or diameter. The hooked end has labeled inner and outer radii, while the round end features a hole labeled with diameter and an outer edge marked with radius. If '5' is on the hooked end, it indicates 5mm radius for both inside and outside curves; if '10' is on the round end, the hole is a 10mm diameter and its outer edge has 10mm radius. All include a 5mm central hole and tick marks to identify curve commencement/end. Gauges range from 1mm-26mm (in increments of 1mm) for metric and 1/16"-1" (with 1/16" increments) for inch measurements.
