Nah,

You just use a cable tie. Wrap it around the filter so the filter undoes as the cable tie tightens. They cost a couple of cents each and the plastic doesn't hurt anything. It works each and every time. I have carried a few of them in my telescope accessory bag and camera accessory bag for this very purpose for years and years.

Cheers,
John B
