I liked this earbud holder because of the quick release feature: the last loop with the audio jack holds the other loops in place. Release it, and you can release all the other loops instantly.

I redid the original as a commented, editable .scad file. I added two central holes so you can thread the cord through them to keep it handy while you are listening.

earbudcard.scad is the source of the .stl and what I actually printed.

earbudBusinessCard.scad is redrawn to be the actual size of a standard business card. Since it works in various sizes, it's the one you should use for your customizations.
