Keep your hands dry and enjoy your beer!
I live in Texas and my beer bottles sweat instantly when going outside.
I love koozies for my beers, but they fall apart pretty quick or can get nasty.
So, I made this simple koozie for my favorite beer right now, Michelob Ultra 12oz bottles, and printed it in TPU and have been using it for over 6 months without a single issue.
I have two versions…
I printed these in TPU so they are flexible and will last longer without issues.
I also tried two printed methods using Cura.
And I LOVE the fuzzy skin much better. It has a better grip, and looks a bit better, but it is up to you.
My final one, not pictured, was printed in black… just a better color overall I think, but having other colors like blue, red, green, orange, etc., for holidays is fun too. :) Throw in a few filament changes and you could have a nice Red/White/Blue or Red/Green or Orange/Black koozie for the holidays or to match your favorite team's colors!
I have not tried this on other beer bottles, so you may need to change the X & Y dimensions. Just print an inch or two to test before printing at max if you don't think your beer of choice will fit.
OH and yeah, not sure what category this really falls under………
cheers!
