I found some labels on here that were for ethernet cables but I had multiple different diameters so they didn't work well for me. My solution was zip-ties.

I used very small zip-ties and I'm not 100% on they type. They are 1mm thick and 2.5mm tall if that helps.

The label "plate" is 12.5mm wide to accommodate 12mm label maker tape.

ADDED a thicker version to fully enclose the zip tie.

ADDED Ethernet Label Final THICKER Intricate which is thicker and hides the zip tie partially. (I have not printed this and you will likely need supports touching the buildplate depending on how you print)
