Bottle Cooler – 100% 3D Printed

On these hot days, even walking to the fridge can feel like too much. That’s why I wanted to create a simple way to keep a cold bottle cool for much longer.

The result is this 100% 3D printed simpledouble-wall bottle cooler: print it, fill it with water, freeze it, and enjoy a cold drink for hours.

This bottle cooler is designed to be practical, easy to print and fully 3D printed. The frozen water inside the double wall helps slow down how fast your drink warms up. It can also be used to cool down warm bottles faster.

The model is printable without supports and comes in 3 different sizes.

Features

• Double-wall cooling design

How to Use

1. Print the bottle cooler.
2. Fill it with water. ( Do not fill it completely, as ice expands when frozen ).
3. Place it in the freezer.
4. Once frozen, insert your bottle.
5. Enjoy a cold drink for hours or use it to cool down a warm bottle faster.

Important Note

Do not overfill the cooler with water. Ice expands when frozen and may damage the model if it is filled completely.

For best results, make sure your print is watertight. Depending on your printer, filament and settings, a higher wall count or slightly increased flow may improve water resistance.

Customization

The outer wall is kept flat on purpose, making it easy to add your own surface structure, pattern, text, logo or decorative design before printing.

Recommended Use

Perfect for keeping a drink bottle cool at your workplace, in the office, at your 3D printing desk, in the workshop or outdoors. Freeze it overnight and enjoy a cooler drink throughout the day.
