Love it or hate it, MakerBot's Smart Extruder has drummed up a lot of press since its launch. Murray Clark, of New Zealand, hasn't had any problems with his Smart Extruder, and recently designed his "Ink Extruder," a ballpoint pen based on the design of the Smart Extruder. Modeled after both the Smart Extruder and a standard Bic Click Pen, Clark designed his files using Rhino3D and printed several iterations using his own Smart Extruder on his MakerBot Replicator 2 and MakerBot 5th Generation Replicator. Clark has made his files available on Thingiverse. Read more about his design and process in the full article: http://3dprint.com/56439/ink-extruder/
