Filament Keychain - AirTag or Pill Box

This is a keychain looking like a small filament spool, either made to fit an Apple AirTag, or as a pill box to store small items. It's not only useful, it also allows you to carry a sample of your favorite filament with you at all times!

There are two versions, one which perfectly fits an AirTag, and one that can be used as a multi purpose container, storing all kind of small items.

Assembly doesn't require tools, simply spin in between your palms until it clicks open or close. I'm always paranoid about such keychains opening on accident, so I made sure the keyring locks the parts in place, making sure it can't open while you carry it, even if the click mechanism wears out.

I tested this with different PLAs - In general, this works better with basic PLAs. Matte PLAs are stiffer and more brittle, making it harder to close and more likely to fail, but they worked in my case (Tested with Bambu and eSun).

I found some materials needing less clearance than others, so I also added a Low Clearance Version. If you print the regular one and find it too wiggly and not clicking well, you should try printing that one instead.
