Insulated Can Coolers

I ran a totally non-scientific, half-assed experiment comparing this 3D-printed coozie to a Yeti, and the results were actually pretty interesting. In the photos you can see how the Yeti’s vacuum-insulated body barely gains heat, so most of its cold loss happens at the top opening where convection takes over. The 3D print doesn’t have a vacuum layer, so heat transfers through the material more evenly, meaning it warms up faster overall, but in a smooth, uniform way instead of a top-heavy pattern like the Yeti. Even with that, after four hours it was only about 4°F warmer than the Yeti, which is impressive for a simple printed sleeve.

Very cool! (sorry for the pun) I was able to modify it to have a slot and an insert so you only need one cooler to handle both size cans. When the insert is top down (like a "u") then I can still fit in 16 oz cans. When the insert is right side up (like an "n") then I can fit 12 oz cans that rest on the insert. The insert just slides out when you turn the cooler upside down (with the lid off) so you can flip it over. I was just barely able to make everything fit without changing the overall dimensions but it might be better to modify the original model to make it 1-2 mm wider. Here are a few pics of some cuts of the model and the final result showing it setup for a 16 oz can and 12 oz can so you can see what I did. Since I didn't change the overall model size the same lids fit and keep the insert from falling out when there is no can present. Thanks for the model @BrentPeterson !

Neat model. Not a fan of the fuzzy skin on this one, so I printed without. A little wiggle room for the cans I've tested, but cans fit well enough. Top fits well. Haven't tested how thermally effective it is, but it's got to be better than my bare hands warming up the can. Thanks! EDIT: For non-Fuzzy skin... Go to Objects (Next to Process), then select Range in the hierarchy. Then go to the Others tab at the bottom and turn Contour to None.

Nice and love the texture but wish it wasn't so tall because it makes it hard to drink & putting a hole on the bottom would help. It was hard to get the can out due to the suction. I ended up drilling a hole on the bottom since it was already printed.

this printed great and I really dig it. I had an idea tho, but my imagination is far better than my designing skills. could someone design a section of the bottom that is threaded internally that when you twist the bottom portion, it raises the bottom inside kinda like a Push Pop to better fit 12oz cans? does that rambling even make sense? is that even possible? I dunno...I don't even frekin work here

Printed perfectly, couldn't have been easier! Excellent fit and finish, and the texture is satisfying to grip in your hand. Compared with the expensive name brand metal options, cold drinks unsurprisingly warm up significantly faster in this printed version. But, most drinks of this size are consumed within half an hour or so and it certainly helps in that timeframe! Plus in high humidity it stops or contains condensation. Thanks for posting this!

do you have a file to print a taller top screw on section? it fits 355ml perfectly, however the standard 375ml cans in Australia it is too short (see left in pic)

Awesome print that came out amazing. Added some text and used two tone filament for the first time. Thank you and great job!

I found out that the 16oz also works very well for 16oz water bottles

perfect fit!! no more cold hands thank you!!
