I made this clip to make it a little tighter than others I found.
Design uses AirTag itself to pretension the clip. Speaker facing outwards for better sound transmission.
Insert AirTag from the back, metal part towards the inside, starting with bottom-back edge.
Print on the flat edge. Design is tricky to print due to wide and thin arc. Tested only with PETG
