The CrazyBad 4x4x5 Cuboid is a center-shifted shape mod of the original TomZ 4x4x6 cuboid, with one of the 4x4 layers truncated. It was designed by Dan Fast (CrazyBadCuber) in collaboration with Calvin's Puzzles. It features a modern mechanism that allows for smooth turning and some corner cutting. Available in Black, White, or limited edition Blue plastic.
