USB Cap for Sony USB key
thingiverse
Replacement lid for a nameless Sony USB key (refer to picture to see if this one looks like your USB key). It's modeled after the original, so it fits on both ends snugly. Requires supports to print, and the supports are a bit annoying to remove, but with some careful side cutter action it's doable.
