To solder all the LEDs together i used alligator clips to help hold everything together.
As i said before, i decided to to this after i built it, so i don't really have any pictures of the building process.
However the pictures below are excally what it should look like. These are from Chr's instructable for his 4x4x4 cube
. Also there is additional information on his that may not be included on mine. So go read his too.
First make all four layers, then solder the layers together.
