Instruments are expensive, but there’s a whole community of 3D printers who are experimenting with printing their own instruments to potentially bring the cost down. There’s a group of students that printed a guitar that was then used by the British indie rock group Klaxons onstage. Although guitar bodies are traditionally made from wood, it seems like 3D-printed guitars actually sound pretty good.

Your children’s imagination

Realize the dreams and fantasies of your children’s imagination in three dimensions with Crayon Creatures, also from Cunicode designer Bernat Cuni. Crayon Creatures, as the name suggests, takes your children’s drawings and turns them into wonderfully terrifying 3D figurines.

New legs for your pet

If your pet was injured or born with a disability, why not help it out? 3DSystems recently printed a set of custom blades for a dog born with deformed front legs so that it could run for the first time in its life. Look how happy he is, scampering around on his 3D prosthetics.

New arms for you

There’s no reason to stop at your pets—there have also been some amazing advances in medical 3D printing. Doctors are making 3D-printed tools to aid in spinal surgeries, working knee joints and human organs. Last year, MakerBot donated to a project that built a prosthetic hand with fingers that can be controlled by wrist movements.

A toy bike made from an IKEA stool

There’s a group of hackers making IKEA products a little more useful, or in some cases, just more fun. They have turned IKEA’s $15 Frosta stool into a toy bike which you can make with just a bit of 3D printing. And the stool, of course.

Snowsports for Generation Z

You can build a seasonally appropriate sled out of a Razor scooter with this mod on the Thingiverse. How long before hacked scooters like these—or custom-build stations—start popping up at ski resorts around the world?

iPhone 6 cases

If you don’t like any of the existing cases for an iPhone 6, you can print one yourself. (Nokia actually incorporated the ability to 3D print new removable cases for the backs of the Lumia 820 early last year.)

Chopstick help

If you struggle to eat food with chopsticks, but are sick of giving in and asking for a fork, you can now get some 3D-printed help. Slip this device around a pair of chopsticks and never drop your noodles again.

Cunicode’s Bernat Cuni spent 30 days designing and 3D printing a different mug every day, for 30 days. Some of the designs are clearly more about form than function. Some are still on sale.

A model of your heart

The National Institutes of Health recently set up a 3D print exchange, where doctors and researchers can upload, search and download 3D models of viruses, molecules, lab equipment, and anatomic models to print. This is more for doctors rather than regular hobbyists, but it’s pretty amazing that MRI scans can now be used to print accurate models of human hearts. Doctors are using these to help plan their strategies for complicated open-heart surgeries before they make the first incisions.

Where to find 3D printers

If you’re trying to figure out where to get your own 3D printer, the options are constantly expanding. Staples has partnered with 3D Systems and Home Depot with MakerBot to sell 3D printers in their stores. Amazon and Best Buy now both have extensive 3D printer sections on their websites. MakerBot has also opened brick-and-mortar stores in the three locations in the US where you can pick up a printer.

If you don’t want to buy your own 3D printer, there are many stores around the world that now offer 3D printing services. 7-Eleven convenience stores in South Korea, the supermarket chain ASDA (owned by Walmart) in the UK and shipping company UPS in the US have varying 3D printing services available for anyone to use. It’s like the new version of one-hour photo service.
