A8 Prusa i3 PTFE Filament Guide

thingiverse

My first part designed! It's tailored specifically for the A8 Prusa i3 clone, mounted on the opposite side of the Z-Axis Limit Switch, utilizing pre-drilled mounting holes for secure attachment. The threaded fitting requires some effort to start, but once seated, it sits flat and even; however, be prepared to "poke" the hole from the funnel with a small round file to fully open it up. It's precision-engineered to accommodate 1.75mm filament, allowing just enough wiggle room for smooth flow without any obstructions. The two mounting holes are deliberately tight, enabling the screw to be loosely threaded in - no need to worry if they're not loose.
