We have a Lista (I think… the branding has come off this cabinet) parts cabinet at work that came with metal dividers. These dividers were pretty terrible for small hardware for a number of reasons, and having a printer I saw no need to pay $1-2 per bin to get this organized. These bins are designed to so that they slot into the existing tracks and don't slide around. They fit fairly close together, but still can be moved easily. One of the upper edges has a lip to help grab it and provide a spot for a label.
Hope someone else finds these useful as well.
