Thought the case by @kyleisah was great but I store most of my tools, connectors, etc… in drawers with a Gridfinity system.
Combined the “Gridfinity_2x4_35mm_solid_Magnets.step" file with the cutout in the case
The author remixed this model.
Used the “Gridfinity_2x4_35mm_solid_Magnets.step" as a base and then utilized the cut out of the JReady Case by @kyleisah to get a similar holder.
