Radius Tool with Gridfinity Base

I needed a tool I could not find (and was happy to procrastinate on the next project by working on this one first). I wanted a quick set of reference radius gauges to use when designing. I needed interiors and exterior curves, and then decided to park them all in a Gridfinity base.

This set covers 10-25 mm sizes, and they all live inside a handy Gridfinity storage box when not in use. The box is fitted to each size, and all slots are labeled for ease of use.

Then, I liked this set so much, I made another set for the 1-10mm sizes in a pocket-friendly package.

Looking now, I see a few similar kits which are all nice. Anyway, here's mine.

Please note This tool gives the radius size, but many cad programs use diameter sizes when drawing circles.
