Summary This is a remake of thing:1135524 I have been looking for one and now I have one of my own. I had downloaded thing:1135524 and found that it was not quite right it was to short and not quite wide enough at the top of the funnel. Now as you can see in the pictures, it is much closer to the ball-bearing and drive. Hope that you like, I sure do, much better for filament load.
