I 3D printed a Fitbit Air bicep mod to wear it under my sleeve
Best of both worlds
For those seeking a screenless tracker, the Google Fitbit Air offers an economical alternative to pricier options like the Whoop band. Intrigued by the possibilities of 3D printing, I recently acquired a Bambu Lab P2S printer and decided to create a custom adapter for the Fitbit Air. However, I faced a challenge with flexible TPU filament, opting instead to print a charging stand for the charging puck.
While researching community-made files, I discovered a Fitbit Air-to-Whoop 4.0 adapter on the Bambu Studio app, sparking an idea to use the Whoop band as a housing for the Fitbit Air. This unconventional placement proved useful, as the longer and more expandable Whoop strap makes it easier to wear around the bicep. I 3D printed an adapter using PLA plastic, which securely holds the Fitbit Air in place.
Despite some discrepancies in metrics, the Fitbit Air surpassed the Oura Ring 4 in sleep time and step tracking. Wearing the tracker on the bicep sacrifices step accuracy, but the Google Pixel Watch remains the best option for precise measurements. Ultimately, I choose to wear the Fitbit Air on my bicep to hide it under my sleeve, while still relying on an analog watch and Oura Ring 4 for accurate health metrics.
