I thought I had a picture of the damaged vents before I removed them, but apparently, I don't. The pictures from under the package tray shows the long tab on the bottom of the part aligned with a slot in the metal package tray. I think this would fix the correct orientation. That tab on your part appears to be shorter than on the original part, so it might need to be lengthened some to use it as an alignment pin. Your part that you printed looks great. Thank-you for taking on my project. Not sure how many folks might need a set of these, but I for one do.
