Print with inside of case down so that the outside will be clean from support material sprue. It will take longer, but work better. I used the latest Cura for best support material. Lines or concentric seem to come off well. Roundy 2 corners and screen protector 2 need to be printed in Ninjaflex (TPU) or they won't fit. Tolerances on the tripod mount may need adjustment. If too tight, filing them down should help. If too loose, melt a couple of small grooves in the edge with a soldering iron to bow out the material just a little to hold it in.
