🧵 PTFE Guide for Existing Drag‑Chain – Easy‑Print Upgrade for Smooth Tube Management

This PTFE guide for existing drag‑chains is a practical easy‑print upgrade designed to keep your PTFE tube securely aligned along the cable chain. It prevents snagging, twisting, or uncontrolled movement of the tube, resulting in smoother and more reliable filament feeding — especially on fast CoreXY printers like the Creality K1 and K2 series.

The design is intentionally easy to print, sturdy, and support‑free. It attaches directly to your existing drag‑chain and adds a clean, controlled tube path across the entire motion range.

✨ Features

PTFE tube guide for existing drag‑chains

Keeps the tube securely in place and prevents unwanted movement.

Easy‑print design

Support‑free, robust geometry — ideal for high‑speed printers.

Improves tube motion

Reduces friction, bending, and unnecessary strain on the extruder.

Compatible with many drag‑chain systems

Especially suitable for Creality K1, K1C, K1 Max and similar CoreXY setups.

Secure attachment

Clips or mounting points ensure a firm hold on the existing cable chain.

🛠 Recommended Print Settings

Layer height: 0.2 mm
Walls: 2–3 perimeters
Infill: 20–30% for durability
