bfb using makerbot extruder

thingiverse

http://www.youtube.com/watch?v=021bGXrXBPY this shows a maker bot extruder on a bfb tool because of how easy it is to get parts and nozzles in the usa. i also created an adapter bracket that holds the top of the ptfe in place when clamped by the plexy glass on top. just for those bfb people that need to send out for another extruder. mine broke last week after clogging. Instructions create 3d part from stl file, put it on top of a build ptfe and brass rod, after assembling triangle below device and clamping, make sure the ptfe is centered so the brass rod does not touch the metal triangle washer. after that wire up ni chrome wire, and use kapton tape, or do the cement again. also if you need to use new wires make sure the wires are not copper, as copper oxidizes to the extreme temp. meaning extruder never turns back on.. so use another metal wire.
