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

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

Bruk.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.

Bruk.gcode prints in 6h 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 Bruk.gcode: https://www.youtube.com/watch?v=qj2Xh6ys8mk

Settings (Cura):

from the start to the end of the cylindrical part:

• layer height: 0.3mm
• line width: 0.6mm
• wall line width: 0.59mm
• bottom layers: 4
• wall line count: 1
• top/bottom pattern: zig zag
• top/bottom line directions: [67,0,134,201]
• skin overlap percentage: 80%
• flow: 120%
• wall flow: 135%
• top/bottom speed: 15mm/s
• wall speed: 15mm/s
• fan speed: 100%
• relative extrusion: yes
• spiralize outer contour: yes

conical part:

• layer height: 0.2mm
• wall flow: 170%
• wall speed: 10mm/s

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
