TL;DR
- Google has released official instructions and 2D CAD drawings for creating custom Fitbit Air bands.
- The company’s guidelines cover everything from sensor placement and mounting strength to safe materials in contact with the skin.
- The files make it surprisingly easy for makers and 3D printing enthusiasts to design their own Fitbit Air accessories.
Google has developed a new design Fitbit Weather to be one of the most accessible fitness trackers, and in keeping with that spirit, the company has released instructions and 2D CAD drawings of the wearable to help third-party brands and creators design their own bands for it.

Now you can Visit this Google Store page for instructions on how to make your own Google Fitbit Air band. On the page, Google outlines the key design requirements of the Fitbit Air sleeve, including guidelines for keeping the sensors flush with the skin for best performance, as well as
CAD design rules. These guidelines cover everything from important mating dimensions and tolerances to mating force specifications, including bond and release force, to help you create a high-quality accessory band.
Google notes that “the arm holder should be flexible enough to allow users to easily insert and remove the sensor. Designers can use a custom attachment to achieve this balance of flexibility and security.”
For what it’s worth, we’ve tested how useful these files are for hobbyists and makers. We asked using PDF drawings shared by Google Claude Can Fitbit Air help convert the geometry of the band into a printable 3D model? The AI explained that while the files aren’t print-ready STL models out of the box, they do contain enough dimensions and tolerances for someone to reconstruct the design in a CAD program.
Claude even made three tapes that suggest he can generate parametric OpenSCAD code, create a detailed measurement reference sheet, or provide a step-by-step modeling guide to help convert 2D drawings into printable 3D files. In other words, with a little effort and some AI help, it’s now surprisingly easy for hobbyists to design and 3D print their own Fitbit Air bands.
In addition, Google shared guidance on the materials that should be used to make these bands, including textiles, leather and metals that are soft, thoroughly tested and safe for continuous skin contact.
By opening up Fitbit Air’s design features to creators, Google is turning its latest tracker into a stunningly maker-friendly wearable with room for endless customization.
