With no included method of attaching AirTags to a keychain, cases are a necessity for most AirTag users. Apple has their own first-party accessories for AirTags, starting at $29, and we’ve done a breakdown of the best AirTag keychains, but many have been creating custom AirTag keychains using 3D printers to fit their own needs.
With 3D printers like the Ender 3 breaking below the $200 price point, they have seen far more use in the home. By heating up a low-cost plastic filament, they are able to build small objects layer by layer. Users create or download 3D models, usually in the form of STL files, from sites like Thingiverse. Using slicing software, you can prepare the 3D model for the 3D printer, adjusting settings such as the layer height and speed to balance quality and time.
With each AirTag case only using a few cents worth of filament and taking a couple of minutes to print, we decided to print and test a few of these 3D printed cases, as well as design one of our own. We printed all of these cases on a Wanhao Duplicator i3 Plus 3D printer with gray Priline PLA filament. We printed with a layer height of 0.1mm and a speed of 75mm/s.
The first AirTag case we tried was a slim and simple, single piece keychain designed by user AnonymousHermit on Thingiverse. The AirTag snaps in and is heldy firmly in place by the rim. It allows both faces of the AirTag to be easily seen, and you can even replace the battery without removing it from the case. With a solid attachment point for a keyring, I would aboslutely recommend this case.
We previously covered another 3D printed Apple TV remote case that is available for purchase on Etsy for $12.99. This Apple TV remote case (first-gen Siri Remote) designed by ururk on Thingiverse sits only at the base of the remote. Only being held to the remote by friction, it is about as small as an AirTag case for the Apple TV remote can be. It avoids adding too much unnecessary bulk to the device and leaves plenty of room around the Lightning port. While I like the simplicity of this model, those seeking a more ergonomic solution may prefer this larger, two-piece print instead. Stay tuned for a similar solution for the new Apple TV remote.
