I have held off changing the fan duct on my Ender 3 Pro and Tevo Tornado until I could do some proper back to back testing. I took the chance to test the Bullseye and a simple vent ring duct.

To do this I designed a torture test file, inspired by the All In One micro printer test. The main body is lifted up off the bed to allow a wide and difficult bridge. There are four gradually tilted arcs, from vertical to 80 degrees, pointing up, down, left and right. The reason to see if a fan that only blows from one side is at a disadvantage. The final feature is a central spire that is raised above the rest.

Next test might have to be the Hero Me..
