Honestly, this was never meant to be released. It's a hacky as hell script that was at first just used for fun, but when I made it only use one brick at a time, someone mentioned it would be useful for building/painting high up. If you see anyone with it that isn't in NWB, BA, or Craftsmen, they either made their own crappy version or someone leaked it to them.
And no, I'm not going to give it to you.
