K-Cup Automatic Dispenser -- Modular

I made a modular version of @curiousgreg's K-cup dispenser. I also added cutouts so you can see how many K-cups are remaining. The idea is that you print one bottom piece, one top piece, and as many center pieces as you want. They all snap together, although you will need to gently sand down the notches so they fit nicely. I used epoxy to bond all of the pieces together, then I sanded and painted the final result.

Changes to original design:

* cutouts in tubular sections to see remaining K-cups
* top piece allows K-cup to be inserted only one way
