Minimalistic AirTag Keychain / Lid

Simple replacement lid for Apple AirTag, that also has hole for keychain ring. Shows the back of AirTag with engraved emoji if you had ordered one.

Detaching the lid profits with even slimmer profile than traditional keychain holders.

This model also features sealing ring like on original lid and supposed to be water resistant.

Model lacks springs like on original lid and tested only with CR2032 battery, but might be working with CR2025 too. If 0.7 mm makes significant difference - you might easily stick some tape on the bottom to raise thinner battery.

Best way to open it for battery replacement is using a flat screwdriver, 3-4 mm wide.

Created as a prototype of snug fit slot for my custom keychain, but turned out to  be good enough to share. :)

Prototype on photos printed with PLA, 0.4 mm nozzle at 0.16 mm layer height. Quick and easy print if dimensional accuracy of your printer has been calibrated.
