Modification for a modification of the QU-BD extruder

This is a modification for DDeGonge888's [V8.0] QU-BD extruder. I found that the ABS filament would for some reason bend and clog up the extruder. This is a little tube that sits on top of the stock Anubis hot end to make sure its reinforced all the way down. There is no "funnel" at the top of the tube so it may be difficult to initially get the filament in.
