Manual modifications of the gcode are required to make Baum watertight, so I suggest printing Baum.gcode instead of slicing the .stl

Upload Baum.gcode  on an SD card and insert it in the printer. Ignore warnings and launch the .gcode from the printer interface.

Baum.gcode is compatible with printers with 0.6mm nozzle and at least 130x130x210mm build volume.

Lower speed down to 50% after the print starts on bowden printers.

Baum.gcode prints in in vase mode in 8h with 30g of Polypropylene (PP) filament.

Apply standard plastic adhesive tape (commonly made of PP) to the bed to ensure adhesion.

Tested with Formfutura PP

How I sliced Baum.gcode: https://www.youtube.com/watch?v=qj2Xh6ys8mk

Settings (Cura):

from the start to the neck:

• layer height: 0.2mm
• line width: 0.6mm
• wall line width: 0.59mm
• wall line count: 1
• bottom layers: 4
• top/bottom pattern: zig zag
• top/bottom line directions: [67,0,134,201]
• skin overlap percentage: 80%
• flow: 120%
• wall flow: 170%
• top/bottom speed: 15mm/s
• wall speed: 10mm/s
• fan speed: 100%
• relative extrusion: yes
• spiralize outer contour: yes

Neck:

• layer height: 0.1mm
• wall flow: 83% 
• wall speed: 10mm/s

Then the 3 gcodes are joined

+ manual and automatic (using using the Python script in readme.txt) X-Y gcodes coordinates shifting, speed and flow adjustments in the area where the neck holder starts printing to improve water-tightness
