This is an organizer for 58mm spring tamper from Normcore. I cut a very small piece of EVA foam to sit down in the bottom of the plate well, so that placing the tamper in wouldn't scratch or otherwise blemish the metal.
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.
