Huxley 3D Printer for $550
eMaker is doing a crowdfunding for a second run of discounted RepRap Huxley 3D printer kits. Huxley is a smaller 3rd-generation RepRap.
I looked at building a RepRap back in 2008, but it was still so cutting edge that I shied away from the complexity. With Huxley, it looks like a much more accessible project. I grabbed one of the first round kits.
