120mm High-Flow/Precision Fan Duct

This is a high-precision 120mm x 120mm fan duct designed specifically for high-performance PC cooling. Standing at 26mm in height, it’s the perfect spacer to eliminate dead zones and concentrate airflow through your radiators or mesh panels.

Engineering Highlights:

• Precision Fit: Exact 120mm footprint for a seamless seal with standard fans.
• Screw Chamfers: Integrated chamfered holes to ensure mounting screws sit flush, preventing interference with PC case panels.
• ABS+ Optimized: Designed with wall thicknesses that handle the shrinkage of ABS+ perfectly, ensuring your screw holes line up every time.

Print Recommendations:

• Material: ABS+ or ASA (Recommended for heat resistance inside PC cases).
• Nozzle: 0.4mm (Standard).
• Infill: 15% Gyroid.
