Murph, how about a Chalkey cup to hold such things. It would of course have magnets from an old hard drive epoxied to the side of a tin. Maybe a strip with holes that would accept 4 or 5 snap rings that could magnetically attach. No need to discuss "I drilled my lower links" or I welded my lower link" discussions from folks like Henro. We could call it something like "Pats Easy Keeper"
