FreezeForm – Ice Mold for Bottle Cooling Rings

Description:

This flexible mold lets you create your own ice rings to cool bottles on hot days – perfect for BBQs, picnics, or outdoor adventures. Simply fill the mold with water, freeze it, and place the ice ring around the neck of a bottle to lower its temperature effectively.

In a test with two bottles filled with 37 °C warm water, the one with the ice ring cooled down by 13 °C in just 15 minutes, compared to only 4 °C without.

Designed for reusability and ease of use, this mold is optimized for printing with flexible filament. The ice ring is easy to remove thanks to the mold’s shape and material flexibility.
