At some point we need to ask ourselves what we really need & what we don't need.
Especially where there is a price (I mean more plastics & supporting the industry/system & environmental impact – not just the current financial cost).
Even if you are creating a display piece and not something functional, it's something you are making for yourself, and a limited number of them. You aren't mass producing Funko Pops of which millions will end up in a land fill.
They've got a lot of space around the can. If the spacing is correct, could slide one of those double-wall vaccuum soda-can holders in there, keep the drink cold. If it's not, could tweak the diameter.
Yes they can easily be scaled to fit them. I have 73mm and 85mm holders. The smaller one is pretty universal for most store bought bottles and the bigger one is more for cups and glasses.
