This was my first ever successful large print.
Base - 15 Hrs
Tower - 55 Hrs
Total time 70 Hrs.
Note: The only reason the tower took so long is I forgot to change the infill settings between prints. I had set the base at 50% infill. The tower should have been at 20% to 25%.
You do not need to print the tower at 50% infill that was a mistake on my part.
