Ice Straw

thingiverse

Drinking straw that's meant to be filled with water and kept in the freezer, then used to turn any warm drink cold as you use it.Unlike ice cubes, ice straw doesn't dilute the drink.Can be optionally used in combination with Holed Ice.This is a prototype, and I wouldn't recommend using it beyond experimentation, as consumer-grade 3D printing isn't considered to be food-grade.
