We didn’t design this model. It’s a community file from its original creator, and now and then a file has a fault that only shows up when we print it, such as walls that are too thin or parts that don’t join properly. If that happens we’ll let you know and try to fix the file, which can add a day or two. If we can’t get a good print from it, we’ll refund you in full.

Good to know before you order

TPU has a £11.50 print-order minimum. ABS, ASA, PC, Nylon and PETG-CF have a £46 minimum; PA-CF has a £69 minimum. Delivery is shown separately in your cart.

Please check the model files include everything you need before ordering. We print the files as published by the creator, so you receive the parts in the model, not necessarily a finished assembly shown in any photos. These are community designs by their original creators; we manufacture and post them but cannot guarantee fitment for your specific appliance or use case - check the original design page for compatibility.

About this print

A filament guide with a built-in roller for the Creality Ender 3, designed to clip into the rear aluminium extrusion profile and support filament as it feeds into the extruder. The roller reduces friction compared to a fixed ring guide. The three-part assembly can be installed without removing filament from the machine. PLA is a suitable material for this functional part, as it provides the rigidity needed for consistent roller operation.

Original maker's notes

By Tomaskom_cz on Thingiverse · CC-BY-SA

A filament guide with a roller for even smoother filament feed than fixed ring. Designed for the Ender 3, easily plugs in to the back of the aluminum profile. T-shaped arm is both lightweight and strong with little material used. Length optimized for good operation with both low and high prints. Also allows you to put the spool holder more to the center.

Prints in 3 parts, extremely easy to assemble. A slit allows for installation without need to pull filament from extruder. Slight protrusions near where the axis is placed ensure small clearance of the roller from the base and smooth rolling; slightly sanding roller edges is still useful, but not required.

For those with trouble slicing the base model (it has some defects but works fine in Cura) or if you want to print it without supports for the teeth, alessi71 remixed the main part here: https://www.thingiverse.com/thing:3218716
I included it here with his permission for convenience and also rotated to optimal print orientation, use the file Base-FilamentGuide_Roller_V2_Rotated.stl

I you're using the Z knob, I made a remix that is longer and compatible with the guide: https://www.thingiverse.com/thing:3387796

Works best together with another of my guides, this one for extruder: https://www.thingiverse.com/thing:3122485
