While AirTags are great for find your keys, wouldn’t be great if you could also use them to organize them as well? While we are at it, maybe throw some Legos into the mix as well. Introducing the Expandable LEGO Compatible AirTag Holder. It is sized to work with the Belkin airtag keychain, but if you need to resize, please find a .step file to allow you to reconfigure to your needs.
As for printing, 0.3mm draft works fine and PETG and PLA both work. I used "Support on build plate only" with painted on supports for the actual AirTag holder, see photos. They all break away clean and easily.
Hope you enjoy!
