ABS is warping for me too. I am trying my luck with PETG. Seems like a better alternative to ABS. I think the only drawbacks is that PETG doesn't bridge well at all and I hear that you have to print a bit slower.

Flatty, so did you reverse your fan and now its pushing air out that new shroud?

Do you know where I can find the other printed parts for the pegasus? I am looking for the Znut traps. I found znut traps, but its under the wooden folder and I dont think those are correct.
