A3 Feeder Improvement

This is based on the A6 Feeder Improvement by Athanasus. Using this assembly it is easier to thread the filament down through the mechanism to the hot end and there is more support for bendy soft filaments.

Many changes have been made to make it fit the Anet A3 and be more user friendly. I have now one assembly that is taken off once the two screws at the bottom are undone. I have redesigned and drawn from scratch the Filament Guide Plate and reduced in thickness the lever to account for the new back plate.

Hopefully if your machine is the same as mine it should fit without any or too much adjustment. I have opened up the filament throat on the entrance to Filament Guide Plate to make it easier to thread the filament from the lever. I used a 5mm drill and just by hand twisted it until it looked the part by giving a better funnel. Maybe, I might change the drawing another time. Once fitted make sure your drive cog is running free in the hole, if not you may have a different size
