Ender 3 Sturdy Filament Guide with Sponge Holder

thingiverse

This is a reinforced filament guide designed specifically for the Ender 3. The models I found online were visually appealing but lacked durability, often breaking under minimal stress - a common issue that arises from the buildup of filament tension. To address this problem, I created my own version and decided to share it with the community here. This custom part ensures the filament enters the extruder motor assembly at an optimal angle when your spool is placed on top of the printer, effectively reducing the risk of breakage due to normal filament stress during printing. It's constructed to be robust yet resistant to excessive force, so please refrain from attempting to use it as a makeshift climbing aid. The guide is intended for attachment to the Ender 3's aluminum frame, similar to the standard spool holder configuration. Before starting your print, make sure you have sufficient screws on hand - the leftover ones won't be enough for this project. This design utilizes 3.5mm screws.
