Sounded really cool but I tried to get in on this and it requires you have a bunch of equipment and I cant seem to be a part of the project without it:
"Let's get started by setting up your new account. You'll need to have:


  • A Raspberry Pi
  • A USB power supply for your Raspberry Pi
  • A PrintToPeer SD card (or a Class 10 SD card that's 4GB or larger)
  • An ethernet cable
  • A 3D printer running Marlin or Repetier (we're still working on MakerBot/X3G support)
  • A USB cable to connect your 3D printer to your Raspberry Pi"


So that was a let down... if there's a way to join in on this otherwise please share how to!
