About this 3D model

Ever tried to completely drain a bottle with a low viscous fluid (e.g. silicone -> expensive!)? print it - srew it on - put it on a cup or another bottle and let it drain ###dimensions### outer diameter of bottle thread: 26.65mm inner thread diameter: 24,4mm thread pitch: 4mm thread length: 13mm (25mm for bottle-bottle) groove for cup (bottle to cup version): outer: 91mm inner: 81mm If you're asking yourself why I designed 2 parts instead of one which fullfils both jobs: if I would have made the thread of the bottle->cup 25mm you would have drops of your liquid in the thread when draining in a cup... ;-)
