Actually I have not encountered many difficulties, I have only improved slicing with the following details:

Spiral Vase 0.5mm (one perimeter)

2mm base

3.8kg material pla blue

print speed of 40mm / sec

printing time 69h

thank Virtox Heatwave realize I could have many details, increasing the soft finish of the surface
