Extruder Carriage for Huxley
thingiverse
This is a work in progress for an x-carriage for Mendel. I used similar PTFE bushings for my build platform with great success so I’m trialling it on an extruder carriage. The PTFE thermal barrier is located with a M6 nut & grub screw. This is the standard spacing so it should fit huxley without modification. Also can be used with my x-axis replacement: http://www.thingiverse.com/thing:4831 Follow my build log on: http://strelly3d.blogspot.com Instructions Insert a M6 nut into the slot to allow a M6 bolt (or grub screw) to lock the thermal barrier in place (If you have a shallow M6 hole on the thermal barrier then the bolt can locate the extruder head in place... will hopefully save recalibrating when the extruder gets fiddled with!) Finally use a short bolt (M6x15) to self tap into the side of the carriage to allow the timing belt to be attached. Bushings: Machine/acquire some 16mm round PTFE into 4x10mm lengths with a 6mm drill (or use US drill size C for a really nice fit). Then simply push them into the recesses with a small drop of glue (be sure to use a length of M6 silver steel to keep the bushings aligned)
