Parametric Radius Gauges

I recently came across [this instructable](http://www.instructables.com/id/How-to-Measure-a-Corners-Radius-Using-a-3D-Printed/) which features a really neat radius gauge set. Having already used a few gauges printed from Thingiverse, I knew this set would be more useful to me because they are so tiny.
> We have used some of the measuring tools available out there, but we have found that most of them aren't suitable for tight spaces since they have a long handle that doesn't fit inside the piece we are trying to measure.
