Sure, there are a million cable winders/organizers/managers available already, so why add another one to the mix? 

I wanted one where I could easily unwind a portion of the cable, because very rarely do I need the full length. If I'm plugging something into my laptop or charger, I don't always need the cable fully extended and it's kind of annoying to fully unwind and wind a cable every time you need to use it.

I whipped up these guys as an alternative to what's currently available. They include a couple notches so you can fix one end of the cable and wind the rest of it up. When you need to use the cable, unwind however much you need and you're good to go. You could also just as easily use these without using the notches, if your heart desires. 

There are 5 sizes available in the model (Small, Medium, Large, X-Large and XX-Large). I measured a bunch of random cables we had laying around and no two are the same diameter. The notches in the winders should fit most cables, but probably not every single one on the planet. Again, use of the notches is not required. 

• Small/Medium/Large - notches to fit cables <3mm and ~3.8mm diameter
• X-Large/XX-Large - notches to fit cables ~3.8mm and 4.5mm diameter

If you do try them out, please let me know what you think - constructive feedback is always appreciated!
