Some tin cans do not have an indented lower lip to allow for easy stacking. This becomes annoying in a crowded pantry. The can stacking plate allows these problem cans to stack up to several levels. I use my set every week when I unload the groceries.

Customizer asks for the diameter of the top of the can which you should measure. It also asks for the height of the stacker. This needs to be 20mm for a can height of 110mm to grip the cans properly and stop them falling over.

The stacker can be printed flat but you will definitely need support. It has been designed to print vertically with the only overhang problem being at the very top. Fortunately any drooping of filament tends to just grip the cans a little tighter - a useful benefit. A raft can help. I find that it is best if the stacker has to be pressed to fit on a can. This way the stacks can be pushed around at the back of the pantry without falling apart.

My initial values are for Australian cans. I am not sure of international variations.
