System for coupling magnets to articles

A modular tray assembly comprising:

• a tray comprising:
• a storage compartment for storing items;
• and
• a plurality of magnetic module holders disposed on a rear portion of the tray, wherein each of the magnetic module holders comprises a slot and a module retention feature;
• and
• a plurality of magnetic modules, each of the magnetic modules configured to be coupled to one of the plurality of magnetic module holders of the tray, wherein each of the plurality of magnetic modules comprises:
• a magnet housing comprising:
• a plurality of apertures;
• a first step on a first lateral side of the magnet housing and a second step on a second lateral side of the magnet housing opposite the first lateral side, wherein the first and second steps are configured to be positioned in the slot of the magnetic module holders of the tray;
• a tray coupling feature, wherein the tray coupling feature of the magnet housing is configured to be deflected upon insertion of the magnetic module into the magnetic module holder and thereafter to be positioned against the module retention feature of the magnetic module holders of the tray such that the module retention feature blocks egress of the tray coupling feature;
• and
• a plurality of deflectable portions that allow the magnet housing to flex under pressure, wherein the plurality of deflectable portions comprises an elongate slot, the elongate slot extending at least partially through a thickness of the magnet housing and being disposed inward of the tray coupling feature;
• and
• one or more magnets, wherein each magnet is received in one aperture of the plurality of apertures of the magnet housing.
