I was requested by family members to make them some cool looking koozies for get togethers. Found MandicReally's grenade 12oz can koozie design on Thangs and absolutely loved it. But I also wanted to make each koozie different for each family member who requested one. So I created a slot on the side of the original design to be able to fit a round badge matching their branch of service. They fit very snuggly so may need some sanding and working with. I used glue but honestly, they're so snug it felt like overkill. I did it this way so that it looks clean when done.
I do plan on creating more badges to fit into the koozie. If you have suggestions on what others you'd like to see, just leave it in the comments and I'll see what I can do when I have time.
I originally printed these with an Ender 3 S1 and just changed the filament based on layer height. So it's totally doable to make these in multi-color without the AMS.
