About this 3D model
Print the petals and shape them accordingly. I used my oven as a heat source here because I didn't have a heat gun at the time. Note that the petals on the middle of the print supposed to fuse a little bit together, I found this as the best solution for the print to be more stable and not to wobble at the top of the print. I cut them apart easily with a scalpel and then started the deforming. I used a 25 line wide brim to print the flower, adds additional stability. Super glue the parts together as you see on the video.
