A USB cable cover, made in 4 parts and screws together without additional items or glue.
This will handle the end plug to about 12mm x 7mm profile, 19mm tall with another 7mm tail and 4mm diameter cable.
If it's too loose in the cover, you can add a slip of paper to hold it tighter. Anything bigger and you'll need to scale it up or edit the design.
