Alternate Filament Feed Pulley

Widened the center of the pulley a little bit and rounded the edges to give it a 'fatter' look. This will mount fine in the original creators bracket, as well as in the alternative bracket I remixed. The diameter for the pin to attach the pulley to the bracket is also unchanged.

Extruder Temp: 200
Bed Temp: 62
Speed: 60mm/s
Fan: 90%

I used a brim since there was not a lot of contact between the pulley and build plate, so I did have to lightly file some minor edges off. I am not certain it was required.
