This shower faucet addon came out pretty good. Its actually what I wanted.
The nozzles are directed to a center point 400mm below the faucet outlet so the water beams flows almost perfectly straght down.
Print in PETG to ensure it will not deform when using hot water.
My filament is green Clas Ohlson PETG
The settings I used
0.2, 20% infill, 2 walls (to reduce print time), variable layer height and 0.12 for the M22x1 thread, no flanged o-ring is used.
The author marked this model as their own original creation.
