I designed this tray to sit on top of my laser to hold material clips. The magnets were added to keep the trays from constantly being knocked off.

One tray has a tab slot on the front to hold an ID label. The magnets I used are 5x3mm and fit in snuggly with enough stick-out to make contact with the surface they are sitting on.

Tray measurements are 75x75x25mm.
