I tried to make the description and the solution in such a way that it could be done easily, without  special program, and knowledge.

Color printing is easy with Z layer height change.

In the picture and example, there is a Jazztronica List for guests coming to our workshop while they wait. =)

The model is similar in width and rounding to the wifi qr code models found here: https://www.prusaprinters.org/prints/62820-wifi-qr-code-with-custom-qr-code , and they look good together.
