We needed a better way to organize our coffee drawer, so I came up with this.  Each hole is stepped depending on what goes in it so they can be rearranged to suit whatever combination of pre-filled and ground coffee you are in the mood to fill it with.

The Inner hole diameter fits pre-filled K-cups and refillable K-cups.  The middle diameter fits 2" diameter containers available at Dollar Tree stores in packs.  Sure Fresh Mini Storage Containers with Lids, 10-ct.

The file dimensions are sized to optimize the space for the drawer I used.  Each cup “square” takes up 70.7mm.
