Ok this is the cube from the movie Cube its 1/2 scale and contains over 4200 7x7x7 rooms. To finish it you should go into MCEdit and just cut out the holes for the doors to each room as i messed up the assembly of this thing and cant be bothered to fix it myself as this was done for shits and giggles. if you do use it a word of warning it goes from bedrock to skytop and id suggest burying it as its pretty unsightly. Not even gonna lie this thing was build entirely in MCEdit minus 1 room. I built the first room by hand then just replicated it within MCEdit.
