Needed a new ball chain holder and wanted one with magnetic retention.
It is designed to use two 16mm x 4mm magnets up to 6mm thick. I trimmed these ones down to size:

I'm using ball chain for a projector screen mechanism that's essentially a giant roller blind and my old chain holder broke (it was kind of spindly). My old holder was improved immensely by wedging a magnet into it so the chain couldn't drift out on it's own sending the screen into uncontrolled free fall.
