Modified QU-BD Extruder lever

I used bdring's extruder lever in my QUBD extruder for quite a while with mostly good results. I found however that it would catch on the raised area of the stepper motor and would not allow the bearing to sit completely tight against the MK7 drive gear that I use. With some filaments that ran a little thin, this led to slipping and clogging.

I also found that if I was using flexible filament, the space between the lever and the drive gear allowed the filament to get at an angle which led
