Google has published the Fitbit Air’s technical specifications and CAD drawings, giving anyone with a 3D printer the measurements they need to design custom accessories for the $100 tracker.
The blueprints include the device’s exact dimensions alongside mating dimensions, tolerances, and mating force specifications required to build a properly fitting band. Google posted the announcement to Reddit’s r/fitbit community, saying: “We know that your personal style is entirely unique – and in just a few short days, this community has already come up with innovative and creative new ideas to make the Fitbit Air your own.”
The move comes less than a month after Fitbit Air launched in early May. The screenless health and fitness tracker sells for $100, syncs with the Google Health app (formerly the Fitbit app), and uses a Gemini-powered Coach feature to deliver fitness data and workout suggestions. It’s positioned as a competitor to Whoop. Users had already started designing their own accessories, including 3D-printed armband adapters, before Google even released the official specs.
