Get ready for summer with this 6-pack ice cube mold and have a cold beverage wherever you go.

Just fill the mold with water, put it in the freezer and a few hours later they are ready to cool your favourite drink. The ice cube fits around the bottle necks and will cool your drink from the top. Like this the cooled down liquid will flow to the bottom of the bottle while warmer parts of your beverage will rise to the top until all of the content is equally chilled.

For a full 6-pack you will need 2 of them - they are split in 2 rows of 3 to accommodate the cardboard handle on your six pack.

They can be stacked on top of each other to save space in your freezer.

Currently there is only one version available for 33 cl bottles that works for 25 and 20 cl bottles as well. There is a 50 cl version in the making but these sizes are difficult to source here. (help! please send proper beer to portugal ;)

To release the ice cube form the mold, simply let them sit around for a few minutes or rinse the mold with warm water from the back if you are in a hurry. There are 2 slits on each side that can also be used to twist the mold slightly to help them release the ice cube quicker. Simply insert a spoon handle or butter knife into these slits and slightly push away from the mold. That should help to break off the mold from most surfaces touching the ice.

- Do not try to break out the cube directly - the ice will likely break in pieces and excessive force might be more than the filament can handle.

Material considerations:

Since the ice will not end up in your drink you can use every type of filament available to you and don't have to consider food-safety.

PLA worked fine in my tests, although it is not very temperature resistant and can crack quite easily if it just came out of the freezer and you hit it on the counter to release the ice - but if you give it some time or rinse the mold with water - it works perfectly.

For rough handling i would suggest PETG or optimally ABS/ASA. These filaments are not as brittle and can flex a little bit, which helps to release the ice. For long term use it is probably best to go with ABS or ASA as they keep their flexibility and material properties below the freezing point.

Happy printing and cheers,
