"Guy Creates Massive, Working 3D Printer in Minecraft"
"Every day it seems someone makes something remarkable in Minecraft. But this… well, this is one of the most remarkable Minecraft things I've seen in a while.
It comes from ItsJustjumby, who has crafted a working, Star Destroyer-sized 3D printer in the game. Watch the video from the start, where he demonstrates it in action, but be sure to stick around for when he zooms out and shows how massive the contraption is, and how many moving parts are required to get it working correctly.
