This is a simple box for seed packets. It has a tight-fitting lid, making it almost airtight.
There are 3 chambers to separate seeds. The sides are angled and the front is low to allow you to read the labels. The lid has a matching angle, making the top straight.
Though this is a simple print, having no curves and requiring no supports, it will take a long time and a lot of filament to print since it's quite large. My initial design was twice as wide, having 2 rows of 3 chambers side by side, but that would have taken up over 350g of filament and taken over 2 days just to print the base. As it is, it's about the longest part I have ever printed and it will store plenty of seed packets.
The walls and floor are 3mm thick. Perhaps they could be thinner, but not that much thinner or strength would be compromised.
2 walls and 20% infill makes this very strong. 3 walls and 10% (or even 5%?) infill might be just as strong but may increase print time.
I printed this in CC3D PLA MAX Grass Green. PETG would be better because this will sit in a shed with high temperatures and high humidity.

EDIT: Very large, flat objects like this may curl at the edges. It's not because you have a bad printer, it's that all molten filaments contract as they cool. It's the layers above the first layer that pull at the edges and cause them to curl. What helps is a wide brim - 16 lines or more. This holds the edges down and resists the curling.
I had some curling in this model, especially the base, and this would have helped.
