This is a 50cl bottle holder for the fridge. It can be used alone or connected in series for better holding a number of bottles. It may work for wine bottles and 33cl bottles too, but I took as a reference a 50cl bottle and haven't tried it yet with other sizes.

I am REALLY happy with the mechanism I used to be able to connect this thing in series with other copies of itself. It works quite well even without cleaning the shape with a knife after printing it. Also it can be put into place either by sliding the pieces or by pressing them together and they don't break easily.

EDIT: there's an improved version of this thing which optimizes the use of material and holds the bottle much better: http://www.thingiverse.com/thing:5117

Print as many as you need.
Connect them in series and put the beer on the fridge to cool.
Drink to it.
