This is a holder for 20 “full size” SD cards and 17 microSD cards.   It's meant to sit on your desk (or in a drawer).  The cards are positioned for easy retrieval.

Printed on SV06 Plus using PETG (because that's what I had on the printer that day).  PLA would be more than adequate.  Pretty sure I used .2 layer height.

Print with the bottom on the print bed, enable supports to support the microSD portion.
