I have places to store most of my printer accessories but never really knew what to do with my spare printer plates.  I am using a Parson table from walmart as my printer stand/table and thought the plates would store nicely below the table. This was designed to work with a #8 wood screw, i used ¾ inch screws.  I installed the backstop to allow the little notch to stick out, you can install in further back so nothing is visible or make the name of the plate stick out.

These were printed for my Bambu plates but you can install them closer or further apart to accommodate any size plate.
