I call these beer bottle crates and beer bottles they can be soda bottles too .. actually anything about that size. I used a RJ Rockers 'Bell Ringer' beer for a model for the bottle - which is pretty much a generic beer bottle as far as I can tell. The 4x6 crates hold 24 bottles. I added an extra 4 bottles for each crate - never hurts to have extra beer.
Caution: Be aware these are in BETA .. meaning they have not been printed yet. I have tried my best to 'get it right' the first time .. but until they have come off of BETA you are ordering at your own risk.
