More details + real setup below 👇

💡 Real-world setup:

This version is actively used on my own printer.

I restored the original factory PTFE routing to work alongside the CFS system.

This enables dual operation:

• CFS multi-material system

• Standard spool holder in parallel

Use it today without CFS — upgrade later without changes.

This upgrade allows you to mount the CFS system on top of your Creality K1 / K1 Max while keeping the printer clean, stable and easy to use.

The Airflow V2 design raises the top by +13mm, improving airflow inside the chamber. This helps reduce heat buildup and keeps printing conditions more stable during longer prints.

The CFS+ version is designed to work alongside the original factory PTFE system.You do not need to remove or modify the stock setup — simply add the CFS system next to it.

👉 Designed to integrate with CFS without affecting the printer’s original functionality.

Developed based on the original Airflow Spacer (30+ downloads and real user feedback)

💡 Works with or without CFSThis system can be used even if you don’t have a CFS unit yet.You can install it as an airflow upgrade first and add the CFS system later without any changes.

🔄 Based on real user feedbackAirflow V2 is an improved version developed based on real-world usage and feedback from the original design.The result is better airflow, easier installation and improved overall stability.

Recommended setupFor the best performance and stability, it is recommended to use 6 Airflow V2 elements (3+3 configuration).A 4-piece setup can also be used if you only need to raise the top glass.
