Following the launch of the lightweight, discreet, screenless Fitbit Air, Google unveiled 2D CAD Fitbit Air blueprints so that users can 3D print their own custom accessory bands for the wearable. With dimensions, guidelines, and specifications supplied by Google, users can create designs that allow for a comfortable experience that doesn't compromise the versatile functionality of the wearable. This means that sensor clearance is imperative, and the design must accommodate the optical heart rate and SpO2 sensors on the base of the tracker, and allow for flush, consistent skin contact. Additionally, other considerations must be made by brands, independent designers and artisan makers, such as gentle pressure and security.
Certified accessories can receive the official Made for Google badge.
What Makes This Trend Stand Out
- Open-source Wearable Design
- Brand-released CAD files create a new personalization layer where users, designers, and makers can shape device ecosystems beyond standard accessory catalogs.
- 3d-printed Health Accessories
- Custom fabrication enables niche-fit wearable bands that balance comfort, sensor performance, and aesthetic differentiation at small-batch scale.
- Certified Maker Ecosystems
- Official accessory badges introduce a hybrid model where independent creators can participate in trusted hardware ecosystems while maintaining design originality.
Sectors Adopting This
- Wearable Technology
- Screenless, sensor-driven devices point to accessory-led differentiation as hardware becomes more discreet, modular, and continuously worn.
- Additive Manufacturing
- Consumer-ready blueprint libraries position 3D printing as a localized production channel for functional accessories with precise fit requirements.
- Digital Health
- Reliable biometric readings depend on accessory design quality, creating space for comfort-focused products that preserve clinical-grade sensor contact.
