This remix is designed to go along the side of the printer. The tab fits under the printer and this way it can't tip over. I use it currently to store my extra stickers that came with the printer as well as whichever plate I'm not using.

It's a remix from a simple plate holder (https://www.printables.com/model/270579-bambu-lab-x1c-plate-holder) - I added the tab to make it nest alongside the printer and not tip over.
