Google has introduced a new approach to fitness tracking with its affordable Fitbit Air device, priced at $99.99, which eliminates the need for a subscription to function. This move positions the device as a competitive option in the screenless fitness tracking market. In a significant step for DIY enthusiasts, Google has also released official design guidelines for the Fitbit Air, enabling users to 3D print custom bands and accessories.
Google Releases Fitbit Air’s Design Guidelines for Custom Bands
The Fitbit Air’s design guidelines provide precise dimensions, tolerance margins, and 2D CAD files, allowing users to create personalized accessories. The tracker consists of two main components: the “pebble,” which houses sensors, batteries, and key components, and the “sleeve,” which wraps around the pebble and attaches to the band. Google emphasizes the importance of sensor clearance, ensuring that optical heart rate and SpO2 sensors remain unobstructed for accurate readings. The guidelines also specify that bands should maintain consistent skin contact and a snug fit to ensure stability during movement.
Google Recommends Skin-Friendly Materials for Custom Bands
Given that the Fitbit Air is worn throughout the day, Google advises using skin-friendly materials to prioritize comfort and safety. The design guidelines highlight the need for secure retention, as the device uses a tension-based snap-in mechanism. Custom bands must adhere to provided CAD tolerances to ensure the sensor remains locked in place during physical activity while allowing flexibility for easy insertion and removal.
By opening access to its design specifications, Google is empowering DIY communities to personalize their Fitbit Air devices. The tracker is already available for purchase, offering a cost-effective and customizable solution for fitness enthusiasts.
