I call these beer bottle crates but that 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.
Safe Harbor Statement: I have placed these parts in BETA. That means that they have not been successfully printed yet. Until that time and have physically examined them I can not guarantee them. This means that during the BETA phase by ordering these parts you are essentially a BETA tester and are working with me to improve the product.
