Prusa I3 Filament Tube Guide

thingiverse

This tube guide attaches to the Prusa I3's top, modified Laser cut model, featuring a chamfered hole for easy tube insertion and clearance. A standard water/ice maker tube is ideal; simply clip it on, ensuring a tight fit. For added security, an optional screw hole is available. Cut the tube to protrude approximately 4 inches and slightly bend its end to maintain proper filament orientation. The guide enables smooth tube movement in tandem with the extruder.
