Magnetic stackable storage box

A stackable open-top storage bin for gaming dice, 3D printer nozzles and parts, or loose magnets. The back is square and the front narrows to a rounded tip with a U-shaped mouth, so you can see and scoop out the contents. Thicker corners hold 5 mm magnets in the top and bottom, and a small bead and groove line each box up on the one below. You can change the size, wall, taper, mouth height and slant, magnet size and fit.
