Arts & crafts just got a lot of more interesting. Whether you're a modern-day Michelangelo or your creativity is at a 3rd grade level, 3D printers enable you to bring your ideas to life. Design a butterfly (like the one above) or put a new spin on pottery. No one else will have the same vase.
GLASSES There's only one thing cooler than Warby Parkers and that's glasses you designed yourself. If you're tired of finding glasses that are too big for your face, make them your ideal size. Your 3D printed glasses will look like they're made for you. You still have to buy the lenses, however.
