Wanhao D7 UV Fan Shroud

The 30 Watt UV LED gets pretty warm and needs to be cooled so it will not burn out. The current models of the D7 appear to run warm after time and it is thought that the issue could be related to the way the cooling fan / hot-sink and airflow interact. The air is drawn in from the cooling opening in the base of the printer but the issue seems to be that there is a very large gap between the cool air entry and the actual cooling fan and heat sink. There is also no good hot air exit and the warm air inside can be circulated back into the fan instead of cool air.
