Modified filament guide for Roberts Feeder

youmagine

I take credit for this modification, but initial thanks go to Robert for his original design that I'm building upon. I've incorporated a 13mm diameter bearing with a collar guide on one end and a hobbed gear on the other. This modified guide features extremely limited clearance to prevent flexible filament from escaping and has a hole in the back where you can insert a pipe cleaner soaked in oil, which lubricates the filament as it enters the Bowden tube, significantly reducing friction. Depending on your specific setup and length of screws protruding from the feeder gear, some minor adjustments may be necessary.
