This is a 3D printed Disk II styled case for the SDFloppy II by Plamen Vasilyov. The SDFloppy II is an SD card reader for the Apple II that emulates a Disk II drive.
This replaces the metal case that comes with the drive. Remove your SDFloppyII from its case and insert it into the base of this case, then slide the cover on top.
Each case is painted to match the original Disk II, with a working latch. The buttons and display are accessible from the front of the case, so there's no sacrifice in functionality.
DOES NOT include SDFloppyII. For that, order one from Plamen. He lists them on eBay as user "plamenvaysilov". See his current listings here.
