Nespresso basic smooth dispenser (stackable)

This work is inspired on http://www.thingiverse.com/thing:601422 and various other good designs out there. I just wanted to design my own stackable version.

For a single non-stackable dispenser I prefer my other design here: https://www.thingiverse.com/thing:1319671

This is another Nespresso capsule dispenser. My personal idea was a smooth filleted dispenser that doesn't hurt your hands with sharp borders, except for this and the FreeCad sources it is very similar to other designs out ther
