These keys can be inserted in the lock hole and help you identify the drives, as well as twist to unlock
Print the pegs separately, then add a drip of superglue and insert into the key, if it does not fit simply sand the edges a little.
DO NOT glue into the key-way on the NAS, it will stay without glue, if it is too loose add a strip of painters/masking tape around peg to make it slightly thicker.
Using a color change at 5.10 (50) you can see the labels better.
