The 22x22 Rubik's Cube was made by a YouTuber with the channel name corenpuzzle. This puzzle was made at his house with a consumer grade 3D printer instead of using the 3D printing com called ShapeWays. Being this puzzle is fully functional, it does qualify for the world record highest order NxNxN puzzle, currently held by Oskar van Deventer with the Over the Top cube, however, this record is not official yet, so Oskar still retains his record. This cube exploded twice. If you would like to see the video of this cube, it may be viewed here:

This cube has been superseded by Grégoire Pfennig's 33x33x33 cube. When this was announced, corenpuzzle was one of the first to congratulate Greg.
