Cover Panel for 5.25 inch optical drive pay on a PC case.

It is currently configured to fit a CoolerMaster Mastercase Pro.

Not all cases use the same hook-length for their Drive-Bay covers. Measure the hook positions of the drive-bay covers that came with your case, and then use the Fusion360 file in the link below to modify the file for your specific case.

Print instructions

Use a modifier block in your slicer that configures the front-mesh to have no top or bottom layers in that section. That way, it will only print infill, making a mesh to partially prevent dust from getting through.

Print face-down with supports on build plate.

I used 0.20mm layer height in eSUN PLA+.
