Cooler/holder for 2 bottles

This model is a cooler/holder for 2 bottles (0.5 liter volume).

The cavity in the middle is where you should put the cooling resource. It can also fit 9 ice cubes(dimensions maximally 25x25x30 mm) put inside a small plastic bag.

The model can be carried like a small bag with the use of the 2 holes that stick out and a piece of rope or a chain.

I wouldn't recommend printing the model with less than 10% infill due to possible structural integrity issues while using the model.
