NCASE M3 Grater Front Dual 120mm Fan Bracket

You can support my works here: buymeacoffee.com

This is a front dual 120mm fan bracket designed for the NCASE M3 Grater.

The bracket allows two 120mm fans to be mounted behind the front grater panel for additional intake airflow. The fan mounting position is offset away from the PSU side to improve airflow clearance and reduce interference with the PSU area.

This version also adds a top screw hole for improved mounting security compared with a simpler lower-mounted bracket design. M3 countersunk screws are required for installation.

Important note:

I do not own an NCASE M3 Grater. This model was made by inferring the dimensions from official specifications, product photos, and measurements taken from the NCASE M2 Grater. Because of this, fitment is not guaranteed. Please treat this as an experimental/modder-friendly part and use or modify it to your own needs at your own risk.

Recommended use:

- M3 Grater Front intake fan mounting

- M3 Grater Dual 120mm fan setup

- M3 Grater SFF airflow optimisation

Can be used alongside my custom PSU bracket, which is designed to provide clearance for 120mm × 25mm fans.

Suggested printing:

- PETG, ABS, ASA, or other heat-resistant filament recommended

- PLA may work, but is not ideal if the bracket is near warm components

- Print with enough walls/perimeters for screw strength

- Check screw depth and clearance before final installation

Hardware required:

- 2x 120mm fans

- M3 countersunk screws for bracket mounting

- Standard fan screws or suitable M3 hardware for fan mounting

Please test fit carefully before fully tightening the screws.
