After printing many of these small boxes, I came across this project: https://www.thingiverse.com/thing:6086763. It has the advantage of being fully customizable and easy to use with OpenSCAD, which is completely free software.

In my opinion, it's one of the best options of its kind. The design is incredibly simple with just a few parameters and options, and it prints without any supports. 

It is important to bear in mind that it is much more efficient to parameterize the object directly in the code than to adjust the scale of the object at the time of printing; the latter leads to modifying all the parameters (wall thickness, screw pitch, etc.) and can make the box difficult to close and does not allow for exact control of the dimensions of the inside of the box.

A huge thank you to Marty Kell for offering this OpenSCAD program for free, allowing everyone to create very stylish boxes with their preferred settings. 

The ability to easily write text on a ring is a significant bonus.

A tip: use a small bar of soap to clean the threads... the box then screws on very smoothly.

Note: compiling the code in OpenSCAD takes quite a while (due to the knurled design). Be patient. The code works; I've tested it several times.

I'm uploading the Prusa GCODE file.
