Stubby cooler with ice holder

Works for bottles, not cans. I design this stubby cooler to be fill up with water and then put in the frezzer for a few hours so the water inside becomes ice and it keep drinks cool for much longer that a normal stubby cooler ( I test it with a room temperature drink and it would also cool it down a bit ) also it have a thin wall in the inside ( so the drink have less isolation from the ice) and a thick wall in the outside ( to create more isolation between the outside and the ice-drink). The top have a thread so you can fill it up with water and the just screw the lid to hold the water inside ( I recommend add some pluming tape or an o-ring to help sealing the lid so it does not leak when the ice start to defrost). Also remmember that water expands around %10 when frozen so I recommend to froze the stubby without the lid or do not fill it up all the way with water to avoid damage to the cooler. You can also use it without water like a normal stubby cooler, due it double wall I think it would still create a better isolation than a normal stubby. Happy printing!!
