After seeing Adrians Geared extruder nozzle I immediately liked it, but realized that it would be even harder to make than older designs

I offer this design as a compromise, that is similar in essence, but using nozzles and barels that can be readily bought from places like Makerbots, ReprapSource, and RepRapStores. Missing from the drawing is the 3mm Plate (because it is identical to Adrians so unnecessary work to duplicate)


To make this all you really need to do is to turn down 8mm of the end of some 16mm dia ptfe to 10mm and put an external thread on it. To make the middle (heatsink) part you use a piece of 16mm dia alu round bar, drill a 6mm hole all the way through the centre, then drill a 10mm hole to 8mm into one end. Tap the M8 and M10 holes. The peek cap is almost identical to Adrians, except It 16mm dia. I made the flange 2mm thinking that would be easier, and put M6 tapped hole instead of a 8mm clearance hole.
