The filament tends to slip out of the hobbed area of the extruder drive bolt on my machine. I wanted to make a new extruder block, either http://www.thingiverse.com/thing:13530 or http://www.thingiverse.com/thing:14317 but of course, because my extruder couldn't be left unattended for more than a minute or two, and this is a big part, I couldn't ever get one finished.

So this is just a little insert that sits inside the extruder chamber, and prevents the filament from being squeezed out. It's dead simple.

Thank you. Thank you. Thank you!
After a mounting pile of failed prints on my Huxley I took a punt on a vague memory and typed "Huxley filament guide" into Thingiverse.
I had been getting suspicious that my extruder jams were being caused by sideways slipping of the filament when I found relatively little plastic in the hobbed bolt teeth and some patches on the extruded filament with no apparent toothmarks.
I managed to print one of these little beauties and immediately managed a tall 3 hour print with no problems.

I shall be trying this myself as well, I am getting fed up setting the extruder to do 400mm to start the filament and then ending up taking so long getting the filiment to bite it goes in by about 50mm! lol Love the simple thought for this :)

Haven't had a single problem with the feed since putting this in - and it's small enough to print even with a badly behaved extruder - hay presto!

Interesting. I was having the same problem with my Huxley. The filament has to come in perpendicular to the extruder face or it'll pop off to the side. I'll have to try this.
