I just had a dumb thought.

It started by thinking, "I could 3D print a 3.5 inch floppy disk that would hold an SD card so I won't lose it."
Then I started thinking that I could 3D print a 3.5" floppy fascia that would hold an SD card reader.
Then I thought, "How could I duplicate the metal sleeve on the 3.5 inch floppy, and how could I make it slide back when inserted?"
Then I thought, "Could I gut a broken 3.5" floppy drive, remove the heads and actual mechanism, but leave the part that opens the floppy?"
Then I thought, "I could do the same thing with one of those tiny USB flash drives, I think... just have the female usb slot inside the 'drive' ".

Anyway, purely for making a modern vintage system, like the nuXT or a Raspberry Pi emulator, I began wondering if A) one could make a fake floppy drive/disk that reads/writes SD/flash, B) how would one go about doing it, C) would anyone be interested and D) would I get lynched by purists?
