Keys go everywhere with us, they’re the last thing we check before we go out, and the first thing we use when we get home. Keychains make keys easy to find, but more importantly, they allow us to personalize these bundles of things we carry around with us every day.
3D printed keychains are an excellent way to take a little piece of your passions wherever you go. Gamer, music fan, or movie buff, 3D printing your own keychain gives you that little reminder of things you love no matter where you are.
The best 3D printed Keychains are down to personal choice, but here are our picks for the coolest fobs you can print at home.
How to Make a 3D Printed Keychain
For the most part, keychains are one of the easiest things to 3D print. They are normally simple shapes with metal attachments to fit on to any keyring.
While there are many fully-designed 3D printed keychains available online, almost anything can be turned into a keychain by adding a notch for a ring onto a smaller 3D printed project like a minifigure or logo.
Even Lego figures or jewelry can be made into keychains with some simple 3D printed additions.
3D Printed Name Keychains
The main benefit of 3D printed keychains is how easily they can be personalized. Some people choose their forenames, surnames, or nicknames to attach to their keys to let everyone know whose they are.
These work well for your own keys, or as a 3D printed gift with a pet name to a loved one or friend.
There are plenty of examples out there for 3D printed name keychains, like this customizable design by SETech.
The Spotify Keychain
Anyone can make and print a cool model that can attach to a keyring, but there’s something special about keychains that are more than they initially seem.
Spotify codes work similarly to QR codes, and can be scanned with a phone camera to automatically play any song on Spotify. This simple but creative 3D printed keychain includes such a code that can be made for any song you like.
Designed as an ideal gift, it makes for a great 3D printed keychain so anyone can carry around a shortcut to their favorite songs wherever they go.
The files here include a few example songs, but they also include instructions on how to find your own.
Light Up Motorcycle
Finding things in the dark or under your car seats can be a pain. Loose batteries and small items from the grocery store always seem to find their way rolling around the floor of your car no matter how careful you are.
This 3D printed keychain is a light up motorcycle designed to fit an LED and a battery to act as a mini flashlight, making it perhaps the most practical keychain on this list.
While it takes some careful engineering, the instructions included with the files here are fairly straightforward and simple enough for anyone to make.
Cartoon Character Keychains
Cartoons are a huge part of our popular culture, delighting and entertaining children and adults alike.
3D printed keychains are all over the internet, letting you carry characters of many different animated shows and movies in your pocket.
The endlessly quotable invertebrate Patrick Star is available as a 3D printed keychain design, as is Baymax, the medical companion of Big Hero 6 fame that we all want to hug whether we know it or not.
The cowabunga kid Bart Simpson is a classic keyring addition, and is available in a variety of 3D printed keychain designs along with the rest of his yellow family. Our favorite of the Simpson family keychains is this 3D printed Lisa Simpson keychain that can be customized with an image of your choice.
Speaking of aliens, you can also 3D print the adorable and destructive Experiment 626, also known as Stitch, for your keyring.
Dragon Ball Keychains
Dragon Ball has been a household name in anime and mange for a long time, so it’s no surprise that paraphernalia of all sorts can be found to buy or make online.
It shouldn’t be surprising that the many recognizable logos as symbols of the in-universe factions and companies are available as 3D printed keychains that have been faithfully recreated from the source material, like the ones found here.
From the Symbol of the dastardly and vengeful Red Ribbon Army that hounded Goku for decades, to the Capsule Corp logo of the company that made this fantasy series a lot more sci-fi.
For fans of the later series, there’s also the Majin M that has become a symbol of evil intent in many designs. The recognizable Z of the franchise’s most popular iteration is also a great choice as a 3D printed keychain for any fan of the legendary show.
Or you can show your true knowledge of the show by making one of these 3D printed keychains depicting the many different schools of martial arts, as well as the Turtle Hermit Master Roshi himself!
Star Wars Keychains
Most Star Wars fans tend to have some sort of memorabilia of the ever-popular franchise somewhere in their homes or pockets. But that doesn’t mean there aren’t some clever 3D printed keychains out there that mark some of the more obscure, or at least rare, symbols of the cinematic giant.
While keychains of the famous logo or the many well-known characters are easy to find, our favorites are these 3D printed keychains that include the symbols of the Jedi, the Empire, the Rebels, and the newer iteration’s First Order.
For a more classic look, here you can find Darth Vadar, Darth Maul, and the old fashioned Stomtrooper helmets as 3D printed keychains too.
Fans of The Mandalorian aren’t to be left out, though, as a 3D printed keychain of the famous bounty hunter’s helmet seen throughout the show and films is included in these files.
Customizable Pet Keychains
These files for customizable pet tags were designed to double as both keychains and collar additions. Anyone who takes comfort in their furry companion will be happy to know that they can carry the likeness and name of their pet around with them.
These tags are very cute and nicely designed images that come with blank tags for your pet’s name. They’re ideal as regular keychains, tags, or to mark a food bowl or leash if you have more than one fuzzy little pal.
3D Printed Videogame Keychains
As with any pastime, videogames can take up more of our free time than we’d like to admit. They can be a great passion for many, and so 3D printed keychains of characters and symbols are available for any who want to bring a little bit of that passion around with them
Mario mushrooms, Final Fantasy logos, and many classic icons of hundreds of beloved virtual worlds are easy to find and 3D print as keychains to show off your preferred fantasy world. Even the logo from Blizzard’s runaway hit Overwatch can be found as a 3D printed keychain.
That’s not even mentioning the hundreds of 3D printed Pokémon keychains. From your favorite pocket monster to Pokémon Go team of choice, there are plenty of options for trainers of any sort to choose from.
3D Printed Car Key Keychains
Many of us take pride in our roadsters for one reason or another, and there’s no better way to express that pride than by carrying our cars’ logos around with us.
While most car key fobs already display the make of the car itself, there’s never any harm in adding a little more obvious flair to our keychains to show of the motors we use almost every day.
Many designers online share in this pride, and so custom 3D printed keychains are available for download all over the internet for any make and even some specific models. So you can show off that VW, Porsche, Hyundai, among many others even when away from the car.
