Tension Nut Filament Guidecommunity.shapedo.com
I added a filament guide, based on my tension nut, so I don't need to worry about the filament looping off the roll on a long unattended print job. The tension nut is tight enough that it doesn't need a screw to hold it in place though you can add one if you need it.The hole has a large fillet on both sides so the filament will pass through easily and the arm should accommodate various spools.You can add a small square of foam in front of it and push the filament through. The foam will clean off any loose dust or particles on the filament before it gets to your extruder.
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
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
Onboard Printrbot Filament Holderyoumagine.com
I wanted to put my filament onboard with my PB LC V2. So here it is. I had to make it in two pieces to fit on my printer. It has to be glued together. I have already made changes to the bottom from what is in the picture. This is still a work in progress.An 8mm bolt will come through the back of the lower half and require tapered hubs with 608 bearings.
Filament Roll Holder / Bracketnunus-world.com
Bracket Designed as a filament roll holder. Bottom piece is 25mm x 75mm x 10mm. The long edge is 140mm long with a single hole for mounting a rod with a screw. The bottom two screws are spaced 1" apart and are 5mm Diameter to give some wiggle room with use with M4 screws. This could also be used as a simple bracket.Filament Roll Holder / Bracket  by rob0tuss1n  is licensed under the Creative Commons - Attribution  license.  http://www.thingiverse.com/thing:619578 http://www.thingiverse.com/rob0tuss1n http://creativecommons.org/licenses/by/3.0/

Adjustable Heavy Duty filament spoolyoumagine.com
The arm and hook are like on the original, but the Hub has been redone to work with both 3 and 6 adjustable arms as well as to fit the Ultimaker mount.Just print a hub and the amount of arms you need to get a super-sturdy filament spool for your Faberdashery (or other) filament. Then print the the following files from http://www.thingiverse.com/thing:33461: fluxline_rod.stlfluxline_cap.stlfluxline_spacer_big_spool.stlfluxline_Spool_mount_V3.stlFasten the rod to the spool mount, the spool mount to the Ultimaker, add the spacer, then the spool and finally the Cap. http://www.thingiverse.com/thing:33461:
