20 - 500 mm Concave and Convex Radius Gauge Sets

thingiverse

I required measurements of extensive radii on a part, but a caliper was incapable of handling it. I embarked on a search for radius gauges that matched my size requirements, yet they were nowhere to be found. Consequently, I conceptualized and designed a set myself. Subsequently, I pondered, "why not create these in smaller diameters as well?" I uploaded a zip file in the files section if you don't require a specific size and instead prefer the entire collection. The central hole is intended for threading radius gauges onto a beaded chain or length of string for ease of transportation.
