Hello, new single-deck dispenser, stackable, they fit over 5 cans of approx 66 in diameter by 115 high, although you can scale the model as needed for other measurements.
for the union of both you need some 5 mm diameter dowels or print a 5 x 30 mm cylinder, model included
It is simpler than the rotary model that I also published:
