Wanhao Duplicator 5S/Mini Extruder Tabs

These tabs are inserted on either side of the extruder clamp to keep material from moving off of the extruder gear. I've added small pieces of felt pads to help guide the filament above and below the gear. They where created to specifically help with TPU filament but should help reduce the amount of wear common in the Wanhao extruder for these printers.
