Tiered Canned Goods Shelves

These tiered shelves are based on some similar ones my wife saw on Amazon, but she couldn't find any black ones, so I designed some. There are 4 shelf options. 1) Regular can shelf with three tiers (top tier can hold larger cans). 2) Large can shelf with two tiers. 3) Half-size large can shelf. 4) Medium-size can shelf with two tiers. There is also a regular can shelf with a cutout underneath that lowers the amount of filament used by approx 50g, but it takes about 30 min longer to print. 

I highly recommend using the print settings as-is, though if you don't want the star-shaped design on the surface, feel free to modify the surface pattern (my wife liked the looks of that one). The other settings were thoroughly tested to give the best combo of strength, speed of print, and amount of filament used.
