Also called a "face turning" 1x1x1 cube.
With some creative stickering you can turn it into an actual puzzle.
Don't let the model image fool you: when assembled the pieces fit nicely together to form a "solid" looking cube.
When assembled with springs the faces can deflect far enough to allow face rotations.
Reccommended material: strong and flexible, color is up to you.
Important notice: This model contains only the core and faces.
You will have to source your own springs, screws and sticker to finish the cube.
There are no caps over the screw holes as the holes are only 6mm in diameter and you can easily sticker over them.
