I found the location of the Ender 3 Pro microSD card to be troublesome at best. My computer came with an SD card reader and no MicroSD card reader and so it seemed to make sense to use an SD card reader for the Ender 3 and so I got a MicroSD to SD extender so it wasn't right under the bed of the printer.

I printed this with PLA on standard settings, nothing special.

• 0.16mm layer height
• 0.3mm initial layer height
• no supports
• no raft, but printed a skirt
• 200 degrees for extruder/50 degrees for bed
• 6 layers top; 6 layers bottom; 3 wall lines
• infill 20%
  Result:
• 1h 26min print
• 10g/3.4m filament

It fits onto the end of the frame where the two screws for the electronics case are attached.

I used the Commando Picture Hanger strips to secure it in place. Plenty strong enough to hold when pushing in the SD card to the reader.
