Ring Size Measuring Set - Customizable

There are some Ring Size Measuring Set but they mostly are in some useless size systems. Especially, when you want to print a ring, you need the diameter to scale the print correctly.
This set is customizable, so you can choose the size system you need.

I also have a stand to store the rings.

For customization, I strongly recommend to use OpenSCAD instead of the Thingiverse Customizer. This is much more performant and causes much less trouble.
