Cooling fan test torture test

thingiverse

I wanted to test cooling fan performance objectively head-to-head, so I designed this part to help. Previously I had noticed the AIO micro 3D printer test did a great job of showing up the flaws of a lack of cooling fan, so I modeled a similar design. The main body is lifted up off the bed to allow a wide and challenging bridge. There are four gradually tilted arcs, from vertical to 80 degrees, pointing upward, downward, leftward, and rightward. The reason for this is to see if a fan that only blows from one side is at a significant disadvantage. The final feature is a central spire raised above the rest. Version 2b was my final design; I highly recommend printing only this version. The others are included for completeness' sake.
