micro SD & SD Card Adapter for Ender 3

thingiverse

The adapter is specifically designed for use with SD and Micro SD cards on the Creality Ender3-3Pro 3D printer. To secure the adapter in place, simply slide it onto the rails at the bottom left of the printer's frame when viewed from the front. This clever design prevents damage to the original socket by eliminating the need for frequent insertions and removals.
