Garmin Varia mount with Airtag for Specialized Phenom SWAT saddle

This version of the Varia mount has space for an Airtag to be hidden between the two halves. It can be secured to the SWAT mounting holes in the underside of the saddle using M5 bolts. It was designed for a Phenom SWAT saddle, but is likely to work with others with a 60mm spacing. The Garmin quarter-turn insert needs to be sourced separately and is secured to the mount using M3 countersunk screws.
