5 Cool Accessories You Can 3D Print for Your Fitbit Air

Google’s Fitbit Air is a solid choice for a personal fitness tracker, emphasizing seamless comfort with its compact, low-profile design. While it might seem superfluous to add any type of accessories to such a simple device, the simplicity of the Fitbit Air actually makes it ideal for homebrew modifications. All you need is a 3D printer and some designs from a site like MakerWorld to create all sorts of useful gadgets like charging stands and strap adapters.

The Fitbit Air itself is a very small device that can be removed from its companion wristband and used elsewhere to suit your needs. Of course, to do this you will need strips, brackets and supports that are properly sized for the proportions of the device. Rather than buying something like this piecemeal, try using a 3D printer to make them yourself, to save money and have more flexibility when it comes to accessories. You can even create adapters to use your Fitbit Air with bands outside of Google’s designs, which can be especially useful if your original band breaks or gets lost.

The Fitbit Air comes with a specialized USB-C charging puck, which plugs directly into the device itself and charges via a compatible adapter. It’s not the biggest hassle of plugging in your Fitbit Air, but using the puck alone means you have to leave the device and its band on your desk, which is a bit of a hassle. If you want something a little tidier, try 3D printing a Fitbit Air Minimal Charging Stand.

MakerWorld user Christianselig designed an easy-to-print, minimalist charging stand with the Fitbit Air in mind, where you can mount both the device and its wristband and keep it off your desk. Insert the charging puck into the center slot, pass the USB-C cord through the back and pass it through the bottom groove to hold the cord firmly in place. Although it’s not required, Christianselig suggests adding non-slip rubber feet to the bottom of the stand to prevent it from being jostled around.

These days, it’s likely that your Fitbit Air will share space on your desk to charge it with your smartphone. Having multiple devices charging on your desk at once can lead to unsightly cable clutter, making the charging routine even more annoying. If you want your Fitbit Air and smartphone to work well on your desk, install them in a 3D printed 2-in-1 charging stand.

Coming from MakerWorld user Euler_3DWorks, this charging station can charge a Fitbit Air and a typical smartphone simultaneously. The Fitbit’s charging puck fits into the slot on the side, its cable exiting out the back, while the smartphone’s cord and plug pass through a bottom groove and up the middle. This keeps the two charging cables clearly marked and separated, and makes charging your devices as simple as plugging them in. It’s also a good way to keep both devices in a single, centralized location so you never leave the house without one or the other.

While there’s no rule against wearing a Fitbit Air on the same wrist as your watch, having both bouncing on the same arm can be a little uncomfortable. But to keep the technology on your wrist in one place, there is an option: 3D print a Fitbit Air watch band clip. MakerWorld user LeonZZ @SnowVi wanted an easy way to wear his Fitbit Air on the same wrist as his watch. So they designed a simple holder for the device that would allow it to be clipped onto one’s watch strap.

The project includes several sizes and configurations for the support. LeonZZ @SnowVi tested the 21-millimeter setup with a Garmin Instinct, Casio G-Shock, and Apple Watch, and all setups were found to be OK. This is a big help if, for example, you want to use a Fitbit Air watch and a Google Pixel watch at the same time. They note, however, that the print-in-place pivot included in the 21-millimeter V2 model can’t hold up to intense workouts as well as the others, and that you should use a different version if that’s your goal.

What you need to know before buying a Fitbit Air is that the included bands are only meant to be worn on your wrist. They’re not sized for larger areas like your bicep, and even if you strap them there, they probably won’t hold as well as an elastic bicep strap. If you prefer to keep your Fitbit around your biceps while exercising, for example, this Fitbit Bicep Strap Holder is a great 3D printed accessory.

MakerWorld user Macrowave wanted to do just that, so they created a remixed version of LeonZZ@SnowVi’s watch strap clip with two docking points instead of just one. With this change, they could attach a simple elastic from Amazon, tying it on both sides to ensure a firm fit. The strap holes fit bands up to 20 millimeters and, according to macrowave estimates, should work on arms up to 15 inches thick, possibly larger depending on the quality and size of the bicep band.

Fitbit isn’t the only wrist-mounted fitness tracker. Whoop is a Fitbit competitor with a screen-free fitness band and has proven to be a popular alternative for fitness tracking fans. For those who have gotten used to wearing a Whoop tracker, but want to start using a Fitbit Air instead, you don’t necessarily need to ditch the Whoop. Simply 3D print a Fitbit Air to Whoop 5.0 adapter.

MakerWorld user Ste3l wanted to create a practical adapter that would allow Fitbit Air trackers to work with a Whoop 5.0/mg strap. The result is a simple project printed as-is that can clip directly onto an existing Whoop band, allowing you to use the Fitbit Air in the same way you normally would with its own band. Ste3l says the adapter should fit all currently available Whoop 5.0/mg bands, although this assumption is still subject to variant testing.
