Just add a sewing needle or 3D print a long thin cylinder.This is great for spools with small hubs. If your spools have large hubs you may need to print the spacer included, depending on your spools, you may need to adjust the spacer. Keep the center the same size and scale the outer rim as needed for best results.This is for the 1kg or less spools. It may support more, but use at your own risk!
Filament cleaner for Ultimakeryoumagine.com
It may be a good idea to lead your filament through a sponge to automatically clean off dust, hairs etc. Couldn't find one for my Ultimaker, so I made a very simple one with OpenSCAD. I think the sponge causes very little friction, so no issues with printing and retraction. I'll see how it goes, maybe change the design a bit.Using the scad-file it's very easy to change dimensions if it doesn't fit your printer or if you want a different thickness etc. I made some stl-files with and without screw attachment and square cutouts./cleaner.stl/ - simplest one, just clamp it on the filament feeder /cleaner_screw.stl/ - can be attached to the feeder using a screw that's already there /cleaner_squares_screw.stl/ and /cleaner_squares.stl /are the same with some squares cut out in sides and back to make it even lighter. More difficult to print though.Cut a piece of sponge and feed the filament through./Just a copy of my thing at //http://www.thingiverse.com/thing:133353 // :)/ http://www.thingiverse.com/thing:133353

The Stilt goes through the hole. Glue the Stilt into the Plate. Then put the Roller on the Stilt - it should move freely. Put the Top on the end of the Stilt - done. Print each part speratly so you don't get spilkes from the retraction. I printed mine with PLA, 210°C, 75 Bed, 50mm/s, 0.1 Layer Height, 0.3 initial Layer height and 100% infill.Happy printing!
Filament dust filterredpah.com
with this part you can keep clean the filament (no dust inside the extruder) 1,75 or 3 mm on your printer. You can place it everywhere....up to you :-)size D24 x 13mmcut out a little piece of sponge (D20 x 10mm) and put it inside the sponge-holder...make sure that the sponge not opposes friction on the filament
