PG35L micro extruder, based on MendelMax v5 by Ultibots http://thingiverse.com/thing:42112
Adjusted the corner between bearing slots and M4 nut.
Comments and adjustments after first print.
Merge branch 'master' of github.com:jcrocholl/kossel
Larger end effector to move diagonal carbon rods out of the way for PG35L extruder motor.
Merge remote-tracking branch 'upstream/master'

Conflicts:
	effector.scad
Pulling most recent versions from jrocholl.

In the process of undoing some of my 'local' changes, I lost a bunch of
reversions back to the originals.

This is a commit, verified via

git diff --name-only upstream/master -- *

to verify we've pulled in everything correctly, and that the repository
is a perfect mirror.

Future changes will be organized so that the only differences needed
all live in configuration.scad, rather than being strewn throughout.
