About this 3D model

This design can be sized up or down depending on the diameter of your desired cord. I really just wanted something for shortening USB cords and things to reduce clutter. The gap in for the slots in the rim to hold the cord ends is 2.1mm for reference. If you need something smaller or larger just resize it accordingly. If you wind it in the correct direction it will not bend your cords too tightly and well help preserve their longevity.
