V1 seemed too generic, so a more interesting V2 of Airtag Holder in a shape of Oreo cookie, and now it is available at https://cults3d.com/en/3d-model/various/hidden-cookie-airtag-holder-for-burton-channel-snowboard
I could not find a way and other model to attach an AirTag to my Burton snowboard with Channel System. Quick model, 3D print and ready for the slopes.
Suggesting to mount it behind the back leg binding at the end of the channel, so it is out of the way and would not slide itself out.
Item itself is single print item, no assembly require, only to attach to your snowboard.
