Hello! Sorry for the delay I enjoyed a nice holiday away and am back to try this again. So I went 2 different routes with design so those are both the latest. Honestly the C shroud does not help much at all. Even though it moves a little air to the back corner it's not enough to consider it an improvement. I've gone back to the regular non C version and am trying to "aim" the air better. I'm getting good strength of air flow but it's aimed behind the nozzle about 2cm. Once I rework some things I'll upload the latest design with a few different heights since I'm using my own MK3 to design the shroud and not every printer will have the exact same nozzle height.
