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
