UM2 Filament Guide
youmagine
Just another aid to guide the filament through the feeder. In combination with Roberts spool holder and extruder, it works well. Print all parts, including guide and backbone screw together. Then put rollers together and slide on the shaft before screwing on the end plate. I used Cura support structure for "filament Guide" part. Holes for cap screws were tapped but they can likely be started without one. If there are problems with the design, let me know so adjustments can be made to benefit everyone.
