2 Litre / Liter bottle handle / holder / grip so it's easier to carry them whether at the supermarket or at home.

Here are two versions of a handle I made to allow us to hold 2 litre bottles more easily. I've also included the bottle-connector part as a standalone model for you to remix with your own custom handle since there are cooler ways to make the handle.

Keep in mind that I rotated this 3 degrees so that it can print without supports, but the handle is still directly above the bottle centre of mass. If you do any modifications, it's advisable to turn it 3 degrees back to make sure it's square in your 3d modeling program.
