Ice-chilled can mug

This updated design moves the ice cavity to the top of the mug to minimize leakage when the ice melts. Cooling Methods: Crushed Ice (Method 1): Fill the cavity with crushed ice. Safer and reduces the risk of cracking. Requires refilling with new ice each time. Print the included "Ice Cover" and "Ice Funnel" for easier filling. Frozen Water (Method 2): Fill the cavity with water and freeze it directly. Use a compressible material (e.g., 2mm foam) to accommodate the water's expansion when freezing. Reduces the need for constant refills but is trickier to set up. Ensure the foam extends from top to bottom and keep the water level 1–2cm below the threads to prevent cracking. Available Sizes (Beer and Soda Can): 330ml (Normal): 66 x 115mm 330ml (Slim): 59 x 140mm 500ml (Normal): 66 x 168mm Printing and Setup: No supports required for any parts. Seal the mug with varnish or epoxy to make it fully waterproof. After filling, screw on the lid and place the mug upright in the freezer. Performance: A beer chilled to 4°C (40°F) can drop to 0°C (32°F) and stay cold as long as there’s ice in the cavity. Enjoy a perfectly chilled beverage every time!
