NOTE: I've made some updates to this model please see listed updates at the bottom of the description.

If you previously downloaded this model, I have updated it with new 3mf and stl files with design changes.

Design Idea

This pivoting filament guide is designed for Ender-3 V3 SE/KE printers. In my current setup I have relocated the spool holder from the gantry and shelf mounted it above my printer. This guide will pivot left and right with the movement of the print head.

Purpose

The guide's primary function is to assist in the controlled feeding of filament, hopefully minimizing any feeding issues.

Printing Recommendations

Use PLA or PETG material for better durability and low friction. A layer height of 0.2mm and a higher infill (around 20-25%) will provide increased strength.

Increase walls to 3 or 4 to help with strength, no supports are needed but a brim can help improve adhesion.

Assembly Instructions

The guide easily mounts to the frame of the Ender-3 V3 SE/KE, utilizing the pre-existing spool holder mounting points.

The two parts print separately then the pivot arm just snaps onto the base. Ensure that the pivot is securely fastened and test its movement to ensure smooth operation once installed.

Currently testing this with PLA to see what the durability is like.

UPDATE: 15 Sept 2025

I identified some issues where the base would break when trying to remove the pivot arm, I have rectified this and updated the 3mf

UPDATE 2: 23 SEPT 2025

I identified some more issues after plenty of testing. Firstly, I discovered that filament would drag through the guide hole when the arm pivots completely to the left or right. To combat this, I increased the size of the guide hole enough to insert a small piece of PTFE tube, The PTFE tube should hopefully rectify this by making the filament path nice and smooth and eliminate the drag. I have also increased the length of the pivot arm by 20mm and width by 10mm.

The next issue I found was the hole in the base of the pivot arm was too big, this left excess play in the arm making it very loose and could also cause the arm to pop off occasionally, so I have reduced the size of the hole for a tighter fit.
