Modular drink dispenser designed by Ljhtom (Javier Hernando) https://www.printables.com/model/390092-extendable-and-modular-stackable-drink-dispenser-t
(not my design, simply sharing my profiles for US can sizes)
Adjusted for easy use on Bambu Labs printers, sized for either 12oz (soda) or 16oz (energy drink, beer) standard US cans.
For a single layer, print the top + pins, base layer ends, and Additional Layer Med.
For a single additional layer, print Additional Layer Med and input (top) layer ends.
For any additional layers (3rd layer +) print Additional Layer Med and Middle layer ends.
If you want multiple layers, but separated, use the output single upper layer end (this should also be used as the base layer if no rows are meant to feed into it)
