Cube organizer parts - the ones I have are white with light gray connectors, not black like in first photo. Some of them broke when I was trying to take them apart, but you can find them on amazon - 16 of them for $6.29, so they're easy to replace! The actual panels for the cubes are the important part and I've got lots of those...
Just search on "plastic wire cube connector" and you'll find them!
