Description
You can fit this to your 22mm watch band, and wear a Fitbit Air for health tracking on the underside of your wrist (it works the same as it would on top of the wrist).
Multiple versions included:
Centered: for wearing on the non-buckle side of the strap
Offset mesh/solid: for wearing under the buckle, on the buckle side of the strap - this is the most centered that the Fitbit tracker will be on the bottom of your wrist. Mesh makes a slightly lighter adapter.
Supports not needed. Print at 0.24mm layer height for a quick print, or 0.10mm for a slightly nicer high quality print.
