Anet A8, Extruder Filament Guide (Modified)

Hi, I am using a different heat-break then stock which doesn't go all the way to the top of the cold side of the extruder. I needed to add a tube onto the bottom of the original part to fill the gap left. this allows me to print with flexible PVA. As with the [origional](https://www.thingiverse.com/thing:1978036), you will need to clearance the hole with a 2mm drill or equivalent.

I used Meshmixer to add the part needed. This is my first successful modification of an STL file so hurray for me
