Prusa MK4S Filament Guide

This filament guide fits perfectly behind the print head and aligns the top feed. It will not interfere with the side to side motion of the print head and is tall enough to be out of the way when topping out your Z axis. The guide helps to keep things from snagging when pulling filament from tall racks above the printer.

The model prints in three parts. The two side brackets are exact mirrors of each other and should be printed with the guide notch up. The bridge part should be printed so that what would be the top is printed face down. This allows for the trapezoid insert to lay on the print bed with its largest side down.

No supports are needed. The model will fit together and hold with a basic friction fit.
