Six-Can Beverage Cooler

Introduction:

• Outdoor gatherings without lugging a bulky cooler? This holds six cans plus ice, perfect for sharing drinks with friends.
• Uses hook-and-loop fasteners to securely hold six 330mL cans—tall or short.
• Pre-freeze with a coolant pack for approximately half a day of coolness (depending on the ambient temperature).
• Pre-chilling beverages will extend the cooling time. If only the cooler is frozen and the drinks are at room temperature, the cooler's cooling capacity won't keep the drinks cold for very long.
• Do not fill the coolant pack above the maximum fill line.

Regarding Leaks and Coolant Selection:

• With proper material settings and printing, leaks are generally unlikely before freezing, regardless of coolant used. However, freezing and thawing the cooler presents a more rigorous test.
• We strongly recommend using a gel-like phase-change coolant (often included free with fresh food deliveries). Because of the gel's low permeability, even with reduced interlayer adhesion, leakage is unlikely. This is an indirect method but very effective.
• Using plain tap water as coolant will significantly increase printing difficulty. The expansion of freezing water during freezing and thawing microscopically damages the interlayer adhesion, creating invisible micro-cracks that may cause slow, minimal water seepage during thawing. Reducing printing speed and slightly increasing flow rate can help minimize leakage, but we haven't yet found print settings that prevent thawing leakage 100%.

Printing Notes:

• Adjust your material flow settings for your filament. A slightly increased flow rate is recommended. Use normal mode; do not increase printing speed using motion mode.
• Imperfections during printing, such as filament residue sticking to the nozzle, may cause minor surface damage that could lead to minor water seepage. Repair these with a dab of super glue or similar adhesive.
• PETG is recommended. Other materials haven't been tested.
