This slim optical drive bay cover is designed to fit the HP Z240 Workstation after removal of the factory-installed HP GUD1N DVD writer. It restores the front panel’s clean look while helping to prevent dust ingress and maintain internal airflow.

Layer height is .2 with 10 percent fill.

For my 5.25 bay covers I used model HP Z440 (and similar) 5.25inch Drive Finned Bay Cover by PeteD (@PeteD_266224). https://www.printables.com/model/866131-hp-z440-and-similar-525inch-drive-finned-bay-cover
