UP! filiment feeder assembly rework 2

I made a large plastic purchase from "MakerBot" and needed to update this part to better accept the varied diameter of the new filaments and to allow a quick change path to swap out plastic colors. You can now pull to the side the filament as the motor is reversed and it comes out of the feeder gear easily and the revers works for inserting the new filament

I added a tapped hole for a M6 spring plunger to control pressure on the feeder gear, this can be swapped out with a SHCS if you want.
