A collection of cup holders that slide between your couch cushions. Free to download https://makerworld.com/en/models/1318086-cup-holders-for-sofa-cushions#profileId-1353638
Also good for composting and making room in your recycling bin
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.
