So, this is a 3D printer that me and my friend, WildCalvinO made. So basically, you put colors of wool into chests and then start the printer, and then it will print that pattern. Here are the list of blocks that it can print.

-Yellow Wool
-Red Wool
-Green Wool
-Blue Wool
-Light Grey Stained Glass
-White Wool
-Light Grey Wool
-Black Wool

I will make a video with further depth of how this works, and so will WildCalvinO. Check out both of our channels here.
