This is a cord winder box that I made for cable management. Print-in-place; you thread the cord through the slots and inbetween the center prongs on the knob.stl, and snap the box.stl on top. Then, you twist the knob to reel the cord in to keep it from taking up as much space or tangling with something else. To unreel the cord, just pull on it from both sides. Showcase below.
*Note: Some of the parts on the initial layer may not properly be sliced in some slicers due to being too thin, so you may have to edit your setting to “detect thin walls” or similar.
