[KwartzLab] Noisebridge & Techshop team up on a 3D printer

[doug moen]

My friend has one, and yeah its fiddly. It's good value for the money, I
think, and a fun project, but you get what you pay for. Expect at least a
week of tuning, diagnosing problems, and upgrading components to higher
quality parts in order to improve the print quality. Eg, new bearings, a
glass build surface (which is standard on the Type A).
