Two years ago, I had made my own wire rope tethers for the telescope to ensure the finder scope, or perhaps DSLR body, would not fall to the ground if they came loose.
I made one new line. This one for the corrector cap cover. Now, hopefully, it won't fall in the drink.
A loose end (no pun intended) from this project was that I had never covered the frayed ends of the metal cable. As I suspected, they would catch on fabric and prick fingers. I covered them with electrical tape..
