This is an old design that doesn't work on some printers because it relies on really tight tolerances. The new design can be found over here: https://www.printables.com/model/256778-micro-sd-card-holder-2
Only print this if you know what you're doing and you specifically want this design over the newer one for some reason.
This case comes with a lid that protects the SD cards from getting damaged or falling out.
I tested the prints on my stock Prusa Mini. I printed the case in Prusament PLA and the cover in Prusament PETG. I recommend 0.15mm for the case and 0.2 for the cover.
The author marked this model as their own original creation.
