Wanhao Di3 Fan Shroud for the Universal Back Plate

This is a fan shroud designed to fit my universal backplate on my Di3. It uses a 40mm fan and provides airflow all around the hot end but still provides good nozzle visability and access. To use this you need the Universal Back Plate https://www.thingiverse.com/thing:2704218

This shroud seems to work fine and allowed me to print the customizable bridging test out to 100mm.
