Print your Minecraft creations!
 

The Python script isn't available yet (a few things left to clean up), but keep your eye on minecraftprint.com for updates.

I want a 3D printer now.

On a somewhat related note: With 3D printers, I won't be able to joke about downloading more RAM (Asuuming they ever get to the point in which they can print something as complex as that)

Dayum, this is really cool. Now where'd I put that 3D printer that pretty much every household has nowadays?

Seriously though, I could build Aperture laboratories, take off the roofs and have my very own Portal toy set! :D
