Grant's Physical 4d Puzzles
From Superliminal Wiki
2x2x2x3
On January 16, 2022, after finding out that Grant had made his own 2x2x2x2 with his 3d printer, Rowan challenged Grant to build a design that Luna had made for a 2x2x2x3 a bit over a month earlier. After work on a new magnet layout, cad designs, 3d printing, and assembly, the puzzle was completed on February 2nd, 2022
In the coming couple of weeks, Grant created a couple of videos show the puzzle, how to move it, and how the new 3C pieces worked.

3C pieces, the special axis, and gyros!
