This is a gridfinity holder for the complete radius gauge set by @GerryPB.

0.5 to 7.0 mm and 7.5 to 13 mm

I found that his case was not quite large enough for the whole collection and didn't fit with my storage schema.

So I created a new one.

Now I can have all of my ducks in a row. (They look kinda like ducks to me.)

I have added a second one for a similar set off of Amazon that includes a place for the gauge handle.
