It looks good but it decreased the fan's performance when I installed it. I put it on the hotend cooling fan and did a series of cooldowns from 260-50C. I did multiple runs to make sure it was a valid test and all runs were within 1-2 seconds of the average. With this piece installed the hotend took 6:08 to cool down, without it took an average of 5:45 to cool down. My guess is that's it's due to the slight inward taper of the shroud. If all you want is a good looking finger guard, this works, but the cooling performance suffered. (I did remember to remove the support ring, so that wasn't the issue).
