The file 'Ender 3 SD To Micro SD 3D Printer Model' is (SLDPRT,STL,SLDASM) file type, size is 503.7KB.
A very simple micro SD card to normal (full size) SD card modification for the Ender 3. No new parts required (aside from the SD card reader), just print and install.
I designed this part so that NO SUPPORTS are required. I hate having to remove supports! Especially in specific geometry where this can lead to breaking the part.
Therefore, just print the part upright like shown in the Cura snapshot image and you're good to go. I had to include a 12 mm brim so that the part is stable enough during printing, but removing this brim is very easy and won't ruin your part.
You will (obviously) need to buy the SD card reader ($10 on Amazon).
I included the SolidWorks files in case you want to make some changes.
