Note:
The Vase_mode_optimised.stl file was designed to be printed in vase mode. No top layers, 3 bottom layers, and 1-3 layers thick walls. Also no infill.
Without following these settings, I cannot guarantee these looks.
The Without_Vase_mode.stl is designed for old or custom non-vase mode slicers/printers. Not recommended if you can print vase mode.
The author hasn't provided the model origin yet.
