Anycubic Kobra S1 Max Fan Cover | 3D Printed Protective Grill | Clean Look & Debris Protection

What this is

This is a protective and aesthetic fan cover, designed for the printhead of the Kobra S1 Max.

It does NOT modify airflow performance, but helps:

• prevent accidental contact with the fan
• reduce the risk of debris entering the fan area
• improve the overall look of the printhead 

Why you might want it

Let’s be honest:

Stock setup looks unfinished and the fan is exposed.

This solves that.

• cleaner visual integration
• added protection for moving fan blades
• safer handling during maintenance

Design intent

The geometry is designed to:

• keep the fan visible
• avoid blocking airflow unnecessarily
• maintain compatibility with the original housing

Print settings

• 0.2 layer height
• 3 walls
• 15–20% infill
• PLA or PETG 

Installation

1. Position the grill over the fan opening
2. Press-fit or align depending on version
3. Ensure it sits flush with the housing

Notes

• This is primarily an aesthetic and protective upgrade
• Does not improve cooling performance
• Designed for safe everyday use
