Dual Roller Filament Guide - Ender 3

thingiverse

This is a remake of the "Ender 3 Filament Roller Guide" (https://www.thingiverse.com/thing:3052488). As I use dry boxes stood next to the printer day to day, and the occasional roll of material I dig out of a cupboard on a side mounted spool holder, I needed something that could wrangle filament coming at it from different angles. I appreciate there are hundreds of these filament guides already available - this was just my attempt back when I started my 3D printing journey. It was also an opportunity to try out Fusion360. You'll need to print the following: 1x Bracket Mount 1x Bracket Plate 2x Roller 4x Spacer You'll also need some hardware: 2x M4 (20mm) Screws 2x M4 Screw nuts 2x 608 Bearings With regards to the bearings, as they are designed for heavier loads, I tend now to pop off the dust covers and remove the grease with a biodegradable bicycle chain cleaner and degreaser spray, or just warm soapy water and an old tooth brush. Remember to dry them throughly. A small amount of spray lubricant (WD40) will evacuate any remaining water and prevent rust. It also makes them spin effortlessly.
