Although I may be wrong but I belive that sombody already made this.
On topic: The server.cs file contains data for about 8 different bricks, not just a 3x3x3.
3x3x4, 3x3x5, 3x3x6, 3x3x7, 3x3x8, 3x3x9, 3x3x10.
If you want you may PM me the package so I can make a more detailed brown townysis. It may be an easy fix.
