I just finished this tonight! The elbow got really wonky for me...it almost appeared to separate from the print . However, it is where I had some minor issues with the support getting weird. Not sure what angle I should have had support set for. I was able to fill in the gap with my 3D printing pen and smoosh it in and sand it a bit. We used our marble PLA overall I am very impressed with the level of detail. The print took 1 day 4 hours and 10 minutes on my machine and the settings used.
