PET Bottle Holder for Cooling in Water or Attaching to Backpack

This innovative bottle holder design serves a dual purpose: it allows you to cool PET drink bottles in lakes and rivers and easily attach them to backpacks. This makes it perfect for outdoor activities like fishing, hiking, and camping. The holder is compatible with standard PET bottle sizes and ensures your drink stays cool and accessible.

Printed with a layer height of 0.1 mm, this model achieves a high level of durability. No support is needed for printing. 

For optimal strength, I recommend using at least 4 perimeters, which are included in the 3MF file.

To use the holder, simply open the buckle at the joint, wrap it around the bottle, and snap the counterpart in place. Multiple holders can be connected with a rope, which can then be secured to the shore.

Special thanks to squinn for the inspiration with his fantastic model!
