Rostock Max Part Fan

The three fan configuration that came with my ball-joint and HE280 hotend upgrade provides poor layer cooling due to not pointing anywhere near the layers as they are laid down by the nozzle.

I used a 30mm blower fan and this shroud to achieve much more acceptable bridging performance. The fan is snapped-in, and one 3/8" screw from the existing fan mount was used to attached it to one of the fan stand-offs.
