SD card adapter holder for Ender 3 Pro. Not suitable for Ender 3 (as the control board is flipped on the Pro).
I didn't like the other holder I found here on Thingiverse so I created my own. It was designed for this specific adapter.
The USB port is not covered.
There are 2 holes on the front, it can be fixed with the screws that came with the machine.
I also added 2 holes on the top to be used with 2 T nuts in the extrusion - optional.
I printed it upside down with the top facing the bed, hence the ugly left side because of the supports, I guess it would be better to print as it is oriented in the stl - it was just 10 minutes faster how I did.
doesn't matter PLA
