Modular Dice Dice Tower

What if your dice tower looked like actual dice?

That's kind of the idea here. Each of the six sides of a standard (six-sided) die have a particular function to play:

1 - A straight chute.
2 - A two-turn spiral.
3 - A funnel (with a few bars to break up and reduce clogging)
4 - Four ramps in rotating succession.
5 - Side entry to bottom exit (see below).
6 - A (semi-)controlled side exit

The #5 doesn't seem like much use, but it's unique in its ability to be turned on its side for use as an exit. Also, one- and two-cube hollow stacking blocks are included so you can build irregular towers (for example, use a 6 to go into a 5, which then drops into another 6), along with a bracket to put between stacked cubes to help with stability.

There's a single base for simple, straight towers; a double base for those like the one just mentioned; and a base connector for making a more complex base if you're so inclined.

The regular-sized catch tray should be good for most purpos
