Anycubic Photon Mono - large failed print timelapse!

In this video we print (x2) a large elbow connector with a thread at one end and a tapered socket at the other end. Although the thread prints perfectly, the other end is less than round. Between the first and second prints I substantially increased the supports for the overhanging opening. However, this was not enough for the large surface area in one of the layers and the supports break free from the layer on the FEP We'll try to fix this with a better design in part 2
