Printrbot Simple Metal Improved Fan Shroud - with hot end heatsink vent

The opening on original design was too small - causing some back pressure from the fan - basically wasted cooling capacity, so I added an additional vent to push air across the Ubis 13S Hot End heat sink.

should help with heat creep (clogging the hot end).

Just finished designing it. Haven't printed it yet. Will update with what i find.

UPDATE: Not quite right. revised model and am reprinting. hold please...

UPDATE: yup, looks good. go ahead and give it a whirl. let me know
