Google Releases Fitbit Air Blueprints for 3D Printed Customization

Google has opened its latest wearable, the Fitbit Air, to the maker community by releasing hardware blueprints shortly after its launch. This initiative invites owners to design and 3D print their own accessories, building upon the device's already swappable band design. Independent makers have already begun sharing printable projects, and Google is now offering official certification for these third-party creations.

The Fitbit Air continues the legacy of the Fitbit product line, which boasts approximately 33 million active users. Functionally, it remains an activity tracker, monitoring metrics such as heart rate and sleep. However, its design differs significantly from previous Fitbit models, with the core sensor unit, referred to as "the pebble," now integrated without a display into a wristband. All health data is accessed exclusively through the companion app.

The pebble's swappable design was a key feature, allowing users to change bands to suit different outfits or activities. While Google provides its own official bands, the company recognized that in-house options might not cater to every user's desire for personalization. Consequently, they have publicly released the physical dimensions and design guidelines for the device.

Google stated that this move is an extension of its customization philosophy, aiming to ensure users have access to a diverse range of accessories for various use cases and to express their individual style. The released package includes 2D CAD drawings for both the pebble and its sleeve, detailing the necessary mating dimensions, tolerances, and attach/detach forces required for a proper fit. Google also recommends using biocompatible materials for any custom accessories due to the device's direct skin contact.
