I bought and built a Makerfarm i3v. My 13 year old daughter and I put the kit together. Since putting it together I have come up with a couple of things I might want to change. Later when I have it doing jobs for me I do plan on building one with a 2'-0" x 2'-0" or 2'-0" x 3'-0" bed on it. Should be interesting. I am still learning right now but I can see how it could be built. I am going to have to learn quite a bit about the electronics, and I plan on running a dual power supply, one for the machine, and one just for the beds. I also plan on changing how the case is as I want to integrate my power supplies into the cars of the printer. Other than that I am really happy so far with it.
