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 see fit.

The pill box was designed in OpenSCAD using the ISO/UTS thread OpenSCAD library from RevK (https://www.thingiverse.com/thing:2158656). The OpenSCAD code is quite ugly, but should work for creating pill boxes of (slightly) other (inner) dimensions.

It brings its own support for the eyelet because the slicer always thought the thread needed support, too (which it doesn't).
