The connected part of the mechanism is a 1x1x2 by itself. Adding extensions onto each end makes a 1x2x3 by itself. Adding further extensions on the flat sides creates the familiar 2x3x3 puzzle. Slider tracks in a puzzle are not very smooth, and because this 2x3x3 model heavily relies on them, the cube does not turn very well.
