Compact Bowden Extruder

This is a few minor modifications of Schlotzz's Compact Bowden Extruder, direct drive 1.75mm. Holes are enlarged. Extra space is added for the end of the screw in the lever which secures the bearing. Room is increased for the stepper motor. Increased the opening for the filament guides. Etc. Otherwise the parts at the same.

There were no modifications made to Schlotzz's lever for this extruder. He has a couple of alternative levers which you can download from his original design of this extruder. http://www.thingiverse.com/thing:275593

I am not very good with CAD programs, but I can generally find my way around graphic programs. The Design.123 files that I used to modify this extruder are uploaded here as well.

Parts needed:
608zz bearing
MK8 Hobbed pulley drive gear
M3 screws
One M3 nut.
One M3 washer
One M5 screw and washer. (This screws into the plastic. No nut is needed. At least it did with my print.)
Short spring

And you may want one or two filament guides the
