Ah that was the problem. ;) No worries I grinded away that little part. Couple of observations on this new design; the left fan-duct doesn't have enough clearance with the ABL probe. I also grinded away a bit on the right side so I can clear the thermistor wires way better and they now sit nicely without having to rotate the heater-block.
Lastly, when checking the air flow, I notice the air is just behind the nozzle (looking from the front), is that by design?
