I saw a video by KipKay that had this basic idea and I wanted to upgrade it. The design is supposed to look like a broken USB cable that is actually a flash drive.
UPDATE
I added a ridge around the part and Added the USB symbol. It looks a bit big I might play with the size. Also added a filet.
This update also does not require glue. Just fray the ends of the cable concealed in the plastic housing and the flash drive will fit snug.
this is the flash drive this is designed for
