Ender-3 Filament Guide

thingiverse

I've tried other filament guides and was consistently disappointed by the fact that over time the filament would wear a groove through the parts. Determined to find a solution, I designed this one with the specific goal of avoiding that issue. This guide incorporates a ball bearing that enables a wheel to smoothly feed the filament, resulting in a significantly smoother feed that prevents the filament from damaging the guide due to friction. This Filament Guide utilizes a ball bearing located here: https://www.amazon.com/gp/product/B07C6FL8TW/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 I exclusively use these specific bearings for any project that requires them, which ensures I only need to stock one size. The cost of printing this guide is $0.34 in filament and $0.60 for the ball bearing. I'm confident that this design will prove to be a valuable resource for someone looking to improve their 3D printing experience.
