After the promising results with the first nylon extruder, we (woutzweers and I) made a new nozzle following reprap extruder size (so a 3.5 mm feed hole and a 0.5 mm extrusion hole). The extruder head consist of a small piece of brass with two holes placed at 45degree angle. The soldering iron has been mounted in the clamp of a milling machine, everything in the following movie is hand-operated.
