This printable adds a clean, hidden drawer under the Cooler Master QUBE 540.
It reuses the original mounting hole pattern of the case, so it bolts on with the same screws and requires no drilling or modification. The ventilated base keeps airflow paths open while giving you extra space to store small accessories (USB sticks, screws, adapters, etc.) or to mount your own dust filter material.

A simple, practical upgrade that turns the unused underside of the QUBE 540 into functional storage.
