Nespresso Capsule Holder

Hi !
I needed a good nespresso capsules holder, not too bulky and with a good capacity...then I decided to design a new one.

--CRITERIA--
The basic criteria for the development were:
a- more then 10 capsule capacity (a nespresso stock is 10 capsulses, then I would like to have a reservoir);
b- auto-keeping design (the capsule at the end shall not drop it self, while I would like something that make easy to take the capsule)
c- stable vertical standing ( i would like something that take space as low as possible, while enough stable to not fall down at the minimum hit.)

--RESULTS--
In response to my requirements I designed a symmetrical (c) vertical standing holder with 15 capsule capacity (a).
In version 1 the req. (b) has been accomplished by introducing a 38mm hole at the base, while a simple 3-4 cm long piece of filament is fitted to keep the last capsule.
A version 2 testing item has been design to have a single piec for all the job, however it has not been impeme
