120mm Radial Fan Diffuser

# 120mm Radial Fan Diffuser

This **120mm Radial Fan Diffuser** is designed to diffuse and quiet airflow from a standard 120mm fan, making it ideal for applications like 3D printer enclosures where reducing drafts and noise is critical to prevent print warping.

## Key Features
- **Dimensions**: 180mm diameter, 35mm height.
- **Recessed Mounting Holes**: Four recessed holes (9mm diameter) allow M4 socket cap screws to be seated 11mm up from the bottom (recessed by 24mm). The required screw length depends on your fan; consider 11mm + the fan's flange thickness. For reference, M4x16mm screws with nuts worked in testing, but verify based on your setup.
- **Air Diffusion and Noise Reduction**: Features 44 'z' or 's'-shaped baffles oriented against the fan's airflow to "scoop" air into redirection channels.
- Outer edge spacing: ~10.383mm.
- Inner edge spacing: ~5.8mm.
- Baffle thickness: ~2.8mm.
- **Central Cone Design**: A tapered cone (100mm base to 28.5mm nose) directs airflow sm
