This is a dual fan bracket for the Printrbot, the fan on the right is connected directly to the PSU and spins 100% of the time. This keeps the metal hotend cool to the touch, stopping the filament from getting soft and creating jams. The fan on the left is just the normal printrbot fan, because is is offset to the left a little bit I created a small deflector.
