Printables re-post of a model I created and posted to Thingiverse on 2022-09-05: https://www.thingiverse.com/thing:5497870

I bought a set of radius gauges (link below) a while back. They work great for my needs, but the holder they came with wasn't very convenient for frequent use.  I designed this rack to hold them all in a quickly accessible, convenient position. The rack also includes a through-hole for a little PCB ruler and a tray for other miscellaneous items.

The design was optimized to line up the top radius of all the gauges in a continuous line, which is convenient for eye-balling a radius on items I'm trying to 3D model.

There are two STL files available for download, one has three feet on the bottom, the other is flat without feet. Otherwise the two models are identical.
