Printed Extruder (Printruder)
by Zaggo, published
After having some difficulties with the Plastruder MK3 which comes with the MakerBot, I decided to try to print a better (i.e. more reliable) extruder with and for my MakerBot.
The design was inspired by the \"Thermoplast Extruder Version 2.0\" from the RepRap project and by photos I saw of Nophead\'s \"Fast extruder\" .
(Update: There's now a 4th part to print: InsulatorRetainer.stl)
