I originally tried a single-guide design, but found that when the hot end moved left or right, the filament would pull in the opposite direction and often become tangled near the spool.
This very simple version is a dual-guide to keep the filament aligned and feeding smoothly. It is also slightly wider (25 mm) to prevent it from sliding along the Prusa rail.
