AirTag Holder for Pet Collar / Strap (flexible TPU)

No special settings required, outside of what you do to print TPU normally. 

I did 3 walls, 15% infill, with 95A TPU.

The slicer setting “Avoid crossing perimeter walls” is helpful if you have issues with TPU stringing.

I prefer to insert the AirTag with the battery cover on the inside, to avoid it accidentally opening. I also prefer to face the AirTag opening towards the inside of the collar. Safety first!
