Tumbler with extra charge 3D print model

A cup for coffee or tea, iced or hot. The idea is that with one dose of instant powder coffee, tea or some other refreshing drink in instant powder version, you have an additional one. All that is needed is cold or hot water to be poured into the dispenser loaded with instant coffee (or tea). I haven't tried how it works with filter coffee, I'll leave that to future customers. Enjoy!
