Inspired by Jangles1981's [gear coaster](http://www.thingiverse.com/thing:1828298), this is a variation with planetary gears. The top and bottom rotate relative to each other, with 4 planet gears attached to the top and driven by a sun gear in the bottom.

You can add an optional outer ring, which is not only useful to prevent your drinks from sliding off the coaster, but it also turns the coaster into a complete gearbox with a ratio of 5:1 between the top and bottom disks.

Here's a [video](https://youtu.be/kvAJooTW0po) of it in action.

Print the gear four times. Everything should fit together easily, although you may need to ream the holes in the gears if your first layer is squashed too much. The hole should be 5 mm. If you print it strong enough, it should be possible to easily take it apart for cleaning.
