Update ! Added STL files model parts
For 3mf files :
For the top and bottom parts, use the print setting: 3 perimeters 4 lower layers 0 upper layers Layer height 0.15mm-0.25mm as preferred I used the spiral vase mode for the figure , so the seam is not visible, use a lower print speed so that the filament has time to cool, and with a 0.4 nozzle, an extrusion width of 0.6 mm
