Extruder Carriage for Huxley

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
