Looks nice. Silver works too as it matches the device. Pretty specific application, but urge you to share it somewhere - someone will find it useful.

I’m curious how it holds up as well. I was printing a little deflector for my air vent out of regular PLA, and on an 85 degree day the PLA warped in just a couple of hours. I finally have a design I’m happy with, I just need to print in a better material and all I’ve ever printed in is PLA.
