Had to make a long nozzle to be able to reach to one tight place. Head of the vacuum cleaner is 30mm and 20mm away from the head it is 31,5mm. So it is a slight cone. The nozzle fits to that kind of vacuum cleaner head. The vacuum cleaner is Putzer central vacuum cleaner.
The model is split in to parts, which you need to glue after the print.
I printed with PrusaSlicer default settings for PETG. Infill 15%, layer height 0,2mm with 0,4mm nozzle. Took 5h 45min to print.
The author marked this model as their own original creation.
