"Couples Therapy" geocache

Here's the STL file and OpenSCAD source code for the GC7DDNV "Couples Therapy" geocache.

There's four holes on each side of the geocache, and a single hole in the bottom. All of the holes have to be covered with fingers, then you can pour water into the top so the log container (a bison container shoved into a cork) floats to the top. Covering all the holes and pouring the water requires a minimum of 2 people, but some people have retrieved this cache using tape or stickers to cover the holes
