Hey thanks JimmyTime! FYI, I have printed the Mask top right portion and...wow, kinda too thick in the 1-2 o'clock fore-head area...probably overly thick everywhere. I'm planing to revisit the model for some tuning (when I find the time). Also I'd suggest a lower infill as that quarter of the mask took something like 20+ hours and (i'm guesstimating) over a third of my 1kg reel (i was over zealous and infilled @ 20%; way too much!) + a heartbreaking amount of support needed. Probably a much better way to split should be employed but my thoughts were overly focused on aesthetic. (You're my first comment ever! - why I wrote you a novel)
Anyways good luck with your print! Any ideas or suggestions you have I'd welcome.
