This is an organizer for 58mm paper filters. This can be turned to the angle of your preference, but is designed to have the cutout facing away, and the filter easily slide against the near wall
This is the Gridfinity version of my espresso organizer. I call this version of Gridfinity "Underengineered" as I have removed the stacking crown and the corner radii. This makes for a cleaner and nearly seamless top look if all of the bins are the same height.
This was originally a tabletop organizer that aligned with an alternating magnetic pattern. I thought that these would work well with gridfinity, as the dimensions were already almost the same at 40mm increments, so I adapted it. If there is interest, I will also clean up and release those desktop files.
Images will be updated when I can.
