I designed this modular spice rack to be stacked as high as you need it. Then a lid is placed on to to allow you to place items on top of the rack. It can be kept on the counter of in the cabinet. All of the pieces interlock well and there is no need for glue. Each section has slots for 4 bottles and a slot for small bags of spices. No supports are required for this print. I tried to make it as efficient as possible to reduce the amount of filament it takes to print each section. It only uses 177g of filament per section. Each slot is 52mm in diameter. If you would like to scale it for larger jars, you can use that as a point of reference.
