Google released two-D CAD drawings and full device measurements for the Fitbit Air on Wednesday to enable custom 3D-printed accessories [1].
This move marks a departure from the typical closed-ecosystem approach of major tech hardware providers. By opening the specifications for the screenless tracker, Google is inviting a community of third-party creators to expand the device's aesthetic and functional options beyond official offerings.
The technical specifications are hosted as PDF files on the official Fitbit store page [1, 4]. These documents provide the precise data necessary for designers to ensure that homemade bands fit securely and function as intended.
"These CAD drawings include crucial mating dimensions, tolerances, and mating force specifications — including attach and detach force — to help you build a high-quality accessory band," Google said on its store page [1].
The Fitbit Air is a screen-free wearable with a retail price of $99 [5]. By providing these blueprints, the company aims to encourage users to develop their own high-quality accessories to grow the product's ecosystem [1, 3].
Industry observers noted the rarity of this strategy. The Gizmodo editorial team said Google is doing something it has never done before by letting anyone create an accessory for the new wearable [3].
Users with access to 3D printers can now use the provided measurements to iterate on designs, potentially creating specialized bands for different activities or fashion preferences without waiting for official product releases from Google.
“"Google is doing something it has never done before: letting anyone create an accessory for its new screenless Fitbit Air wearable."”
Google's decision to open the hardware specifications for the Fitbit Air suggests a strategic shift toward a 'prosumer' ecosystem. By leveraging the 3D-printing community, Google can effectively outsource the research and development of niche accessories while increasing user engagement and loyalty for a low-cost device.
