The file 'SD Card Holder / Wallet 3D Printer Model' is (stl) file type, size is 1.3MB.
Simple remix of @Natalucciu's excellent SD Card Wallet (v2, magnet edition).
I increased the hole size for the magnets to 3mm diameter x 2mm thick - nothing wrong with the original... that's just what I had in stock.
I also added the text "SD Cards" to the cover.
