New duct design, Take 1

9 min benchy test with new duct. Test the duct slow first so I don't get my hopes up. There are some issues on the start of the roof, small, but there. Need to make an angle change more downward. Impressed for a 1st iteration, hope it get's better.
This is an old file, not sure the acceleration. 500mms, maybe 30K, 20-50SCV, can't remember. Tops are slower at 300mms. Stack printed too slow, ate up 50 seconds!
