This was intended for the Panasonic HJE-120 earbuds but probably works with others.
Can be printed with supports laying flat (stronger) or without supports standing vertical (weaker).
- Slip the aux plug through a hole and pull so that the earbuds are in the center of the square.
- Wind cable around the outside of the square.
- Keeping tension, stick the aux plug into the center and through a hole so that the wound cable holds it in place.
