Reloading/Case Storage

I'm new to 3D printing so be kind.....:-)
I store my cases sized, primed & ready to load & sorted by how many times they've been fired.
I wanted a way to store them which didn't take up too much space, was stackable, was easy to see what was what & easy to just grab however many I need for that loading.
Obviously it's not a radical design but the size was important & fits my .308W cases perfectly.
Made from PLA+ & works for me just fine. Don't know what else to say.
