This Airtag holder includes a cutout channel for a 3mm diameter piece of Paracord.

Print Instructions

Pause the print at 5.0mm and add a dab of glue to each channel - and firmly squeeze in each end of the cord. You might need to use the end of a flat hard object to reduce glue on fingers!

Layer Height - 0.15mm

You'll need around 17-20cm of Paracord in total - something like this is suitable:
