Freezable Can Carrier ChillBuddy – Portable 3D-printed 4-Drink Cooler

This portable 3D-printable cooler box is designed to keep up to four standard cans chilled wherever you go. A central hole connects to an internal water-distribution system of small channels, allowing water to be poured in and drained out while promoting even cooling across the four separate compartments. Fill the box with cold water, freeze it until solid, and enjoy a lightweight, electricity-free cooling station that keeps cans cold for hours. Patreon supporters also receive Fusion360 files, fine-tuned print profiles for BambuLab and Anycubic, and crisp product photos for use in their own shop or on social media; the design has been tested and optimized.
