Bernis simple ninja enabled Mk 7 3d printing bowden extruder

I like Bernis simple design. So much so that i remixed it to fit the Mk VII wheel. It is, how ever, a smidge to simple. You can't really run ninjaflex with it, it makes a yarn in the extruder. So in this new remix. I added a 3.5 mm tall "Tab" to guide the filament in to the bowden tube.

As you can se in the pictures it worked like a charm. Even though i ran with my old printrbot+ settings :)
