Dual Filament Guide for Printrbot with Aluminum Handle

thingiverse

I've redesigned my original single filament guide to work seamlessly with printers that feature dual spool hangers. Sometimes, filament would escape over the edge of the spool during prints. This issue was particularly problematic on longer prints, as it would eventually cause print failures when the filament wrapped tightly around the arm of the spool holder. My revised filament guide slides onto the front of the Printrbot's aluminum handle and secures the filament in the center of the spool as it's pulled off. To ensure a snug fit, I've carefully matched the dimensions to those of the handle. You may need to file or carve a small area for a smooth initial fitting.
