Ender-3 SD Card gap filler
thingiverse
This will fill a gap between the SD card slot and the outer case on the Ender-3, ensuring that the SD card can't slip into the case.\r\n\r\nYou may need to rotate the model in Cura as I've shown in the picture.\r\n\r\nThe part requires an M3x10mm screw.\r\n\r\nThis appears to be unnecessary for newer Ender-3 machines.
