Small Keychain Pill Box

For when the sudden need arises: this small keychain pill box holds a single headache (or other) tablet up to 13 mm in diameter and 6 mm thick. I added a "double" version for anyone who has the need for more than one pill. And the version without eyelet lets you either just keep the pill in your pocket or can be a storage container for small parts. In that case I don't like the grooves on the inner part (now beeing the bottom part). So I added a smooth version of it.

Combine the parts as you
