To print this vase, you will need to use a raft with supports for printing the base only due to it not being totally flat. Make sure if you do that set supports to only touch build plate. The rest of this model prints fine without supports. Alternative Method: Cut off the bottom .48mm of the model with software, make sure to repair the model and all holes after. Something free like Ideamaker software if perfect for this situation, simple and fast. This will allow you to print directly to the build plate without raft or any supports, which is how I printed this. My settings were .4mm nozzle, layer height .1618, 60mm/sec speed, 30% infill, 5 top/bottom layers, 3 shells. No supports, no raft.
