Yeti Rambler can adaptor

I'm a big fan of Yeti coolers and love my stainless steel Rambler cup but sometimes can't be bothered to pour my beer into my mug and would like to use it as a awesome can cooler. So reverse engineered two different Yeti covers and morphed them into a nifty can cooler cover!

The inside lip should press onto a can with some difficulty so it is retained inside the cup when it's tipped.

Enjoy, JEFPL8
