This is the latest version of my 4x4x2.
It is a fully functional corectly propotional 4x4x2 cuboid
Compared to previous versions so is this puzzle much smoother and stable. In other words, more usable.
In order to assemble a 4x4x2 you need a 24mm eastsheen 2x2. You remove the corners from the 2x2 and glue the centers of the 442 in their place. You should leave two centers out until you've assembled 3/4 of it.
If you feel unsure about the assembling, send me a message and I'll see what I can do.
