I'll finish it up and post it sometime soon.

Did you ever finish this up? 

I have issues with black flakes resting on my natural filament from solidoodle.  They feed into my extruder and stand out on my prints. A filament bushing that could easily hold a sponge could be the perfect solution.

These look wonderful! I would say that enough users feel that they can print with the case, that we haven't felt much need to develop these ourselves on a permanent basis. Do you think it helps a great deal?

The main issue I was solving was to stop the filament from jumping over the edge and tangling.  I like some of the fixes other users have come up with and the new one you guys changed to, but for what I have I felt this would do just fine.  As I was sketching different ideas of how to mount it through the hole I thought I would give threads a try since some were asking, and added the inside funnel as well to eliminate any scraping dust getting into the extruder.  Hopefully I'll get some time this weekend to incorporate Ian's sponge design before I upload the STL's.

Sounds awesome.

I finally had some time in front of the doodle yesterday and I thought I'd take the lazy way out of fixing the spool tangle issue that I'm having with this new filament.  Plus I wanted to try threads so I killed two birds with one stone.  In addition to removing tangle, you remove shaving from the 3/4" hole and from the top edge of the frame if you're printing sans case. 

It works well, but I will lengthen the male end a little and make a smaller diameter funnel on the female end.  The inside funnel as printed came dangerously close to the z screw, and the outside funnel diameter is a little larger than the clearance in the case when you want to have that mounted so I will make some adjustments and post the STLs once I've got the bugs out.  30 minute print each side with solid fill. 

1st attempt at threads and they went together but needed a little shaving here and there to get started, I will make seperate prints of the threads to debug them before printing the finals.

You could get a fine sponge, cut a circle out to fit the guide, and cut a slot in the side.  Then after putting the filament through the guide, you could slot the sponge onto it and slide it into the back of the guide.  The outside of the guide might need a slight lip to keep the sponge in so retractions don't push it back out.

Sometimes it seems like the filament spool accumulates static electricity, so it might be a little more prone to getting dusty than you would think.  Enough so that there are a dozen or so filament cleaners on Thingiverse.
