I couldn't find a Jensen replacement vent cover for my camper vent so I remade the original. I had to split it into two parts so that it would fit on my Creality Ender 3 Pro.

Also, I included the Jensen part number so that if in the future for some reason I can find one to buy using the part number it will be available on the part.

I drew it up in Fusion 360 and included the f3d files for both the two piece and one piece vent cover if you have a printer that will accommodate the print.
