I picked up a spare AC vent as I begin preparation to unload the AC parts. I figured I should do this next as summer is almost here and several people have inquired about the AC. One tends to forget that AC is a big deal after living in a mild climate. I intend to sell it as a package, we'll see how that works out.
I met up with a friend today to get some AC vents. My CSI vents are in poor shape and my 3D printing project halted with a low quality parts scan. I acquired an extra vent free of charge. He's going to keep the E3 vents and sell his E3 AC setup. If anyone with an E3 is looking for AC, PM me.
Settling any questions on the difference between E3 and E9 AC Vents. They are the exact same vents with the E3 cut slightly shorter. As other's have observed, the pattern embossed on the E3 vents is slightly less noticeable, but they aren't perfectly smooth.
