Fitbit Air pebble clip for normal watch band

An adapter that clips a Fitbit air pebble to a normal watch band. Enables wearing the fitbit air together with another watch on the same watch band.

Various sizes options are provided. I tested the 21mm option with a Garmin Instinct, a Casio G-Shock and an Apple Watch and they all fit.  There's also a 26mm version which fits wider bands, for example Apple Watch Ultra or Garmin Fenix 7X.

Note: the print-in-place swivel on all V2 versions are not strong enough to hold the pebble in place during intense movement, so please use the V1 and V3 versions for sports tracking to avoid losing the fitbit!  

V1-longitudinal and V3 are the most recommended ones based on my own usage.
 

• V3: better and more durable hinge that won't break. Still print-in-place.
• V2: added swivel hinge to the band loop to enable more comfortable wearing positions.
• V2-longitudinal: based on v2, but the pebble sits lengthwise along the band.
• V1: one piece, no swivel
• V1-longitudinal: based on v1, but the pebble sits lengthwise along the band.
