A simple tool box, inserted between display and mounting plate. Gaps between base and box are 0.3, print box in 99.7 scale if tolerance of your printer is low. It needs suppots, tree is perfect.
UPDATE. i checked geometry with this accessory https://www.printables.com/model/711231-ender-3-v3-ke-filament-spool-side-mount-toolless, it will not comapatible with original plate. I will make new version soon
UPDATE 2. If u dont use side spool holder https://www.printables.com/model/711231-ender-3-v3-ke-filament-spool-side-mount-toolless u can use model “base for original display plate.stl”
