Description
Based on OhmEye MicroExtruder, configured to use 608 skate bearing and zenith HEC1063 corner brace along with other hardware I had at hand.
Instructions
Based on OhmEye's extruder github.com/OhmEye/RepRap/tree/master/extruder
geared extruder and hobbed drive from 2engineers.com
Local hardware had a different L bracket and as I had no 605's I altered this to suit 608'z and a slightly different fulcrum location. the extra plastic piece is to offset the mount hole for the L bracket to swivel on.
Many have reported reliability issues with this geared drive, ensure fully greased up, and also watch acceleration. I believe the biggest issue lies in peak acceleration retract to extruder, causing tooth failure.. as per youtube.com/watch?v=Ft2PxD-q7aU

where did you buy the little geared stepper? Do you have a type number for it?
Times Brilliant 42BYG48HJ50
http://www.2engineers.com they are presently showing out of stock, however _hp_ will be back approx 26 nov or so with the stock at hand being able to be sent then. Note that this stepper has some issues with the final drive gear being brass, and not handling high acceleration. whether the stepper is useful at lower acceleration is what I will be testing
