Ender 3 Filament Guide - Dual Roller

After moving my filament spool to the side of my Ender 3, I wanted a filament guide that would be versatile enough regardless of where the filament was, or how high/low the X gantry was.

With this side spool holder (https://www.thingiverse.com/thing:3492877), the spool reel was going to hit most of the other designs I found.

INSTRUCTIONS:

STEP 1: Choose which orientation you require: Vertical and Angled.

STEP 2: Choose how you want the bearings to fit.

• Version 1.0 - Small spacers - Will fit into bearings with ease and will require a screw and nut.
• Version 1.1 - Large spacers - Will fit into bearings after some post-processing sanding.
• Version 1.2 - Large spacers with slit - Allows for a push fit of the bearings.

STEP 3: (Optional) Use a matching cover. The cover is not required if the bearings are press fitted tight enough. The absence of a cover allows easier loading of filament.

CHANGE LOG:

Version 1.0 (Original Remix):

• Moved the bearing mounts closer towards the extruder, to clear the spool.
• Integrated the bearing spacers into the base and cover, with a press fit, so no extra hardware is required. I retained the holes, in case you wish to add a screw for extra security.
• Aesthetic changes.

Version 1.1:

• The spacers were slightly too short and loose for a press fit. Main body Vertical and Cover version 1.1 updated with slightly larger spacers to fit more snug into bearings.
• Created a main body with a 45 degree angle. Allows filament to always roll on both bearings with a direct input into the extruder.

Version 1.2:

• added slots onto bearing spacers for easier press fit.
