Here’s a clever upgrade on the staid, boring button: you put a little hook behind it so it can keep your headphone cords in place. It’s pretty simple, but considering how many people walk around with headphones every day, it could make a huge difference. It’s a 3-D printed object available for $3.28 from Shapeways. It’s an improvement on the button for a specific use that probably never would’ve been dreamed up had it not been for widely-available 3-D printing. I mean, you can probably wrap the cord around a normal old button and it will do the same thing, but customizing your gear–and that includes clothes–is always cool.
