I designed this door vent in order to be able to prop the door open for more chamber cooling. This reduces the noise from the printer but allows increased airflow.
8mm x 3mm round magnets are used to secure the vent to the door, to the printer, and (optionally) to the side printer while not in use. Each magnet hole is ~6mm deep so they can be double stacked for strength.
The magnet on the edge that touches the frame of the machine attaches to a magnet inside the frame of the printer so you will need to pay attention to the correct orientation of that magnet.
