Awesome, please to hear that your getting better results.
Come to think of it, I have recently had trouble with thin parts warping also, so I can imagine that orientation is a bigger factor than I had previously considered.
And I'm guessing that resin properties may also be a factor? I'm yet to really play with orientation and different resins.
A Nostromo is on my list. Where did you get the file?
This is going great! I am still very impressed by the lack of print lines. Using greeblies to hide joints makes a lot of sense. The clear resin looks amazing. There are probably other great ways to use it.
