This print is designed to be use with the Command™ Cord Bundlers, a commercial product (I have no affiliation with Command™ products other than being a satisfied customer).
This design allows you to combine the portability and re-usability of Command™ Cord Bundlers with a headphone hanger.
You can use whatever print settings you like, but you'll probably need supports for the loop. Use the orientation shown in the printer pictures.
I used PLA at .3mm resolution with 15% infill.
