Wrap the cord to your headphones (or any other) so it won't tangle. A few ways that work for me are pictured, but you may have to experiment a little to find out what works best for you.

I based the design on a headphone peanut that I carved from wood (pictured), but the design slices just fine. Slic3r estimates the volume to be 1.4 cm^3 (19.5 cm of 3 mm filament), so it should be a quick print as well!

Tips, while never expected, are always appreciated. Thanks!

Carved from wood and polyurethane-coated. Should print easily, and would look particularly nice if printed from LAYWOO D3 with layered temperature variation.

Print one in every color to match your outfit/gadget/mood!
