      You can now:

      I have a bill of materials for other parts. That said, it is a pain in the butt and not much cheaper than buying the kit for $399 right now.

  2. Ben Evans says:

    I’ve got one of these and it’s pretty good. I will say however, as with anything, this cheaper little one leaves a lot for the user to do, and as such is more of a hobbyists tool. But if you are a hobbyist, this little guy is perfect for getting started in 3D printing.
