Hi every one, am I the only one to think that sodas are sugar saturated and who want to lose weight ? This straw allows you to drink tasty and healthy beverages with an instant infusion even in a cold water ! Moreover it reduces the waste of plastic while using a regular disposable straw. Printing this thing you reduce impact of plastics on oceans. Please save our earth, for arctic bears and your children ! Use only food grade PLA. ABS and other filaments could be dangerous !
