Behold, the multiple beverage cup. never again will you have to decide between orange juice and milk again. Now, you can have both at the same time. Unfortunately, you might have to have both at once...I recommend using two straws. Please pick a material that is suitable for use as a cup. Look at shapeways' materials page for information on that.
Fair warning, this isn't exactly tested yet (will be soon though). Also, it cannot be printed in some materials as it is too thin. If you have issues finding a material to print it in please send me an email as I am uncertain which materials shapeways will allow this to be printed in. Please enjoy, and do not mix beverages that you should not normally mix (milk and orange juice for example), unless you for some reason feel the need to be adventurous.
