Concept: This idea come up after analysing that many time in our life or in different location of world water which is around us is not drinkable (apart some particular cases). Therefore we decided to design an object which is cheap, simple to print, sustainable an useful for the filtering function. The shape is meant to be particular functional but the triangles which are useful to avoid to drop the object are based on the same corners of the water molecule 104,45 deg. to remind the function of the object to its use; to preserve the most important resource of this planet which allows life: Water.
Note on assembling: It is possible to print the object in a separete way and then assemble them by putting the top on the filter and the filter on the container and a collector under the block you have created. then it is possible to remuve the top and fit it to the bottle which is designed to fit it and create an armonic passage due to the tangency. A more carful approach must be used when it is going to add the material to filters:
in the filter which is close to the collector it is important to add to that filter a sediment filter (which are balls made in ceramic). The second filter is a particulate filter (which are glass balls) and the last is the active carbon (close to the top). Each of this filters must be wrapped in tissue filter. This filters can be bought easily on many online website.
