This is a remix of this carabiner: https://www.thingiverse.com/thing:1008943
I really liked this carabiner for my keyring. I thought i could get rid of some clutter and integrate the airtag directly into my carabiner. Well it works.
You need 4 M2.5*6 Screws to assemble the thing. I didn't wanna make it snap together since the airtag has to come out for a fresh battery eventually. so... yeah. you could remove the screw holes and just glue it together for a cleaner look.

Integrated an airtag for convenience
