For all you coffee lovers out there, I have the "brewanator". All is needed is the coffee grounds, filter, and hot water. Simply remove cap by twisting handle ~17 degrees and lift up. Add coffee filter and coffee grounds, then pour hot water. When done, simply remove filter and replace cap.
The production model may have a fine screen filter part that can be washed and reused, instead of a paper disposable filter. For the 3D print challenge this can be printed with "strong and flexible plastic" or "ceramic". In production mode I envision a hard plastic that is temperature safe for boiling water and safe for drinkable consumable liquid.
The "Brewanator" yields a minimum 30 fluid ounces or 919CC of internal volume, even higher fluid volume if you go above brewing section. This coffee container can be used for any drinkable liquid such as Juice, Soda, Tea, and water. Has a built in Straw then opposite side is a drinking mouth piece or a spout to pour into a small glass or cup. This is a great feature for no spilling of Coffee, juice, etc.
