I don't know if this will work for other USB sticks too.

The measurements (metric) should be fine to import into your slicer and the prints don't need supports or brim.
The infill settings don't matter since it all counts as shell anyway.

You might want to superglue or tape both parts of the body together, since they can slide apart very easily.
I like to keep it as is, because I can the it apart and see the raw USB stick if I want.
