This snack tray includes a cup holder, and it accommodates 500ml bottles and cans with 6.8mm diameter perfectly! The tray allows for easy transportation of snacks, and reduces risk of spilling, and is also stackable, and it also features a phone stand that can be easily attached and printed onto it as well, so it means you can store your snacks on the same tray that holds your phone! Furthermore, it can double as storage bins when you are not using it. Also, when you print the phone stand or cup holder, you should also print a 1x1 or 2x1 bin to hold it, or else it wouldn't work.
