Great idea! With a few refinements I think It'll be a keeper. Even with 50% infill and a very hot extrusion, you will probably experience some leaks. All is not lost, however. I might suggest taking the infill down to 35-40% and instead buy some 'tool dip' liquid rubber compound from the nearest hardware store, or even Home Depot, Lowes, etc. After printing and curing at low heat for a few hours, pull the 'cork' and pour in a generous amount of the 'tool dip' rubber compound. Twirl the item around a few times and make sure it goes all the way to the bottom. Before it has a chance to setup, invert the unit and let the excess rubber compound drain back into the tool dip container for another use. Leave uncorked and in a warm area for a few days, and the compound will have firmly setup inside. Obvious benefits of this approach are no leaks and the tool dip itself will adhere very well to the inner print yet remain pliable. Going to print one up myself and post pics. : )

If you scale Grande down to 85%, it fits a 12oz Redbull perfectly. Also, A 6hr sauna soak in my dehydrator @65C made for much less leakage.

Can someone add some custom supports for the bottom? Also, with 4 walls AND 50% infill, mine leaked.

Great design, and it made a beautiful print. However, it took 24 hours with 4 walls and 50% infill. Also, the overhangs underneath are a bit of a mess. I tried to generate support for the bottom only, but could not figure out how to do that in Cura or Meshmixer. Can someone add some custom supports to the bottom?

Good idea.
Can you make one for beer?
I know that there are several beer bottle types but I live in Portugal and like the Sagres Radler that is 33cl.
I don't know if you have access to beer bottle with 33cl that occur to be the same format as in Portugal.
I can give help with measures.
Be well.

Use math and the scaling feature of your slicer to make a custom sized one.

I printed the "tall" with PLA on the Prusa i3 mk2, at 25% infill, taking 22 hours. Same result after printing it twice! Looking good!

Nice concept and great aesthetics, unfortunately like others, mine leaked :(

This is fantastic. I'll likely print a few of them.

I am interested in making something a bit similar, but based around getting the maximum cold. Did you leave open spaces so it looks nice? I think I'd design for ideal coldness before anything, so I'd probably keep the ice close to the inside and then have shells of sorts between the ice and the outside, for insulation.

I'm also tempted to make a version that's actively cooled, with a peltier disc, etc.

Annnnyway, excellent design!

very nice concept but bottom leaks

great build, but grammar game atrocious.

considering the designer is from Taiwan, writing in english, they seem to have done very well. You are just an asshole.

I really, really like it.

But I had trouble printing the bottom of the part where the angles are less than 45 degrees from the build plane.

I'm really really glad you like it ;)
Please set higher infill over 50% and also higher number of shell like 3 or 4 and try again, you'll see it works much better.
Good luck !

Wait, how does deodorizing work?

Lemon is natural deodorant that works well, is cheap and usually easily accessable.
Use lemons squeezed into water then have lots of left over lemons.
Take the sqeezed lemons or even a slice of one and put it into KEEPCOOL.
It's great, natural, cheap deodorant.
It is not quite as strong as the coconut oil, but works good on a normal day.
Hope useful for you.

Very nice. A version for beer bottles would be great. Probably like the Grande size, but narrower for the bottles.

Thank you for your suggestion.
If you need, you can measuring diameter of the bottle you need and choose one of the size to do small scale so you can have the one more fit you need.
Also you can use the flex material from Makerbot so it will really tightly for your bottle.
Hope you will like it.

Hi skywurz
It has been printed by MakerBot Replicator 2 use PLA material, layer high 0.25mm 50% infill took 16 hrs.
It works very well.
Hope you will like it.

sweet thats what i wanted to know i was thinking about flex for the plug but will have to play with it thanks again

Flex material from Makerbot also can tightly for your bottle.
Have fun ;)

Build by any type of 3D print no Additional support need.
It Has been printed "tall" by MakerBot Replicator 2 use PLA material, layer high 0.25mm 50%infill took 16 hrs.
It works very well.
When you going to print this, layer high 0.15~0.25mm should be fine raft is better to use and best to use over 50% infill.
Hope you will like it ;)

printing instructions and material detail would be nice
