Design Concept

This filament guide is designed for attachment on one side of a 3D printer rail, optimizing space and ensuring smooth filament flow without tangling. I remixed this from "Creality Hi Original Spool Holder Desk Stand Filament Guide" by Maslinka because I found that the attachment ears would hit the print head when it was at maximum height potentially damaging the printhead. This design has the screws at the back and the front uses a thin filament "hinge", so you have to choose the model you want to use if you want it on the right side or left side.

Use

The guide helps streamline the process of feeding filament into your 3D printer, reducing friction and ensuring a steady, reliable flow for high-quality prints. I used this guide for printing TPU and attached the Teflon tubing from my Sunlu FilaDryer to the guide so I could keep the filament dry.

Printing Advice

I would use sturdy material such as PETG for durability and flexibility. A layer height of 0.2 mm is recommended for a good balance between strength and fine detailing. I used CR-PETG and found it flexible enough to work well. I would not use PLA as it would probably be too brittle to flex without breaking. PLA+ may work too, but I haven't tried it.

Assembly Instructions

Simply attach the filament guide to one side of the rail. Ensure it is securely fastened and that the filament path is smooth and unobstructed. With this design you only need two M4*12mm screw and M4 nuts.
