Rubik's M-cube with the fewest components ever created

And here it is. The cube with the fewest components ever created.

I have designed an alternative Rubik's cube (2x2x2). It has only 8 pieces covering a spherical magnet. I think it should feel nice on the fingertips, working fast and smooth. You can see the construction video on my Youtube channel.

The magnetic iron filament for 3d printing can be found at 3dfilaprint.com and the neodymium magnet can be found at supermagnete.com.
