I created a storage bin for Keurig k-cups in my RV pantry. By maximizing the vertical space between pantry shelves I can store more k-cups. I also created a smaller bin for shelves with less height. These are essentially generic bins to store anything you want. The large bin is 210mm in height and the small bin is 170mm. Scale as desired.
I uploaded a version of the bins with front slots which may make it easier to open pantry drawers for example so you don't have to get a finger between the front of the slider and the bin.
