Same mod, it's both the maker and stamper combined. What it does is automagically craft 3x3 or 2x2 recipes from the input.
However, I like your idea much better, now that you have mentioned it.
Will use! You could probably use an iron chest in the middle, stead'a double chest.
You can The layout just ended up working better with the double chest since I needed five autocrafters and still get a way to put stuff in the chest. I pump all the XYcrystals into the one chest and pull out the storage blocks form the same chest because the autocrafters pump there completed work back into the chest too.
